Resonance Definition and 659 Threads

Just a qns, how does resonance work? i know about the natural frequency stuff, but why and how does it occur? why in the 1st place do every object has a natural frequency and different natural freq. And by the way, if we know the natural frequency of a man, couldn't we potentially can kill...

Hello All, I have been playing around with this digital oscilloscope and function generator that I am using at school. I first connected the function generator directly to the oscilloscope to get the hang of adjusting it, then I took a small coil I had laying around and connected it in...

This is very important. Can someone tell the dependency for the resonance frequencies of bubbles? i.e if know a bubble's diameter, the surface tension, the liquid and the gas' densities how do I calculate the sound wave frequencies that causes a resonance in a bubble. I have Landau's formula...

I am not able to intuitively sense the concept of resonance. Let us say we have a building having a fundamental frequency of 5.5 Hertz . If the ground moved to and fro(during an earthquake) with a frequency of 5.5 Hertz, the building would vibrate strongly, or resonate.Right? I am not...

Hello everyone! I've been trying to derive the expression w = sqrt( (1/(LC)) - (R_l^2 / L^2) ) where w is the resonace frequency, L is the inductance of the inductor, R_l is the resistance in the inductor, R is the resistance of the resistor and C is the capacitance of the capacitator...

I need help with a question about acoustic resonance. Sound of wavelength 20cm is produced at one end of a 32 cm long tube. Is it possible for resonance to be produced?

Here's the situation: you have a pipe in a bucket of water and can vary the length of the air column in the pipe by raising or lowering it. Here's my question, hope someone can help. The speed of sound in helium is three times greater than the speed of sound in air (340m/s). Under these...

"A tuning fork with a frequency of 440 Hz is held above a resonance tube partially filled with water. Assuming that the speed of sound in air is 342 m/s, for what heights of the air column will resonances occur?" f1 = 440 Hz v = 342m/s I'm not sure if this is referring to an open pipe, or a...

i got 2 qn , 1 on archimedes principle and the other on resonance 1)The Artic Ice cap is a floating ice mass. If the ice were to melt, how would the depth of the ocean change? my ans was that it will become deeper but the ans was it will remain the same...why? 2) my understanding is...

I'm reading a few papers on resonant captures, and I come across the terms strong resonance and weak resonance, without actually seeing them defined. I've got my guesses. I think 3:2 and 2:1 are considered strong, and I believe that it's because objects in 3:2 and 2:1 will complete a...

Hello, My teacher and the textbook seem to be conflicting with each other, and I would like to know who's right. The image on the left was scanned streight out my my textbook, saying that the third resonance is 5/4 lamda. On the right, is an edited version of the textbook image,showing what...

I made an experiment in a tube, 75 centimeters. There was sand in it so I could distinguish one wave length. the biggest one I got was 0.335 meters at a frequency of 480Hz and the smallest was 0.07 meters at a frequency of 2000 Hz. I calculated the resonance in the tube as 1.5 meters as the...

I'm researching theory, resonance. All I found was resonance as the name of phenomena although I need to figure out who and when it was advocated. Does anyone know when resonance was advocated by whom? I found the term harmonic resonance. Can anyone help me?

i have undertaken an investigation, where the aim is to establish a relationship between the frequencies of an earthquake, and the height of the building(at maximum deflection parallel to motion). to do this, a model was created; a building of lego blocks and a vibration generator set to...

I'm researching theory, resonance. Anyone knows who and when advocated theory resonance and how it developed? It may not be appropreate in this forum, but I heard we have theory resonance in psychological aspect. Please help me!

There's a metal cylinder from which water is flowing out at a rate of 10^-6 m^3/s. A tuning fork of 300 Hz is placed on top of the cylinder. At what water levels will the first two resonance frequencies be heard? It doesn't seem like a difficult problem, and it really isn't. I just can't seem...

Please help me with this, it's one of the 'basic' problems and I can't do it at all. "The chains suspending a child's swing are 2.00 m long. At what frequency should a big brother push to make the child swing with largest amplitude?" Okay, so... the largest amplitude comes with a natural...

In an Oscillating system,as damping increases, the amplitude of the system at the resonance frequency decrease and the resonance frequency also decreased. However why does the reasonce freq decrease? I know how to solve for the new amplitude and ang. freq. mathematically but i do not know how to...

In a question, I've been asked to find the general solution of the equation: \ddot{x} + \omega^2{}_{0} = cos( \omega t) (\omega , \omega_{0} > 0, \omega \neq \omega_{0}) I've found the solution to this. It then asks me if this solution exhibits resonance. What does this mean and...

I am asked to explain why an oscillation spring will eventually begin oscillating in the horizontal direction, i.e. become a pendulum, and I am asked why a mass that is too great will not become a pendulum. I know the answer to the first part of the question. The spring has a natural tendency...

NMR rf Field hi all, could anyone help me explain how the rf B1 field in an NMR spectrometer works? Especially the mechanism it uses to flip the net magnetisation by an angle of 90 or 180 degrees? Would be very gratefull for a link or and explanation to this. Thanks Wadings

Greetings--I'm looking for data on estimates for the Higgs resonance width and I'm not quite sure where to look. I've checked the "Review of Particle Properties" and the Particle Data Group website, but I couldn't find an estimate for the higgs width. Any suggestions? Thanks, Flip

Why does everything have a natural frequency at which it oscillates when struck by a single force and then left to oscillate? Does everything only have one? Does it vary depending on what the original force to cause it to oscillate was? Also, why does force imposed at natural frequency casue...

Given a system where a damped spring has natural frequency equal to the frequency of the input oscillations, how do I choose a damping constant in order to maximize the response of the spring? Are there any issues with choosing a zero damping constant? (as this would surely provide the...

ok I'm definitely having trouble with this lab due tomorrow. We did a lab in class where you get an adjustable tube and use different tuning forks. With the different frequencies of the forks we adjusted the tubes until it reached resonance? (loudess point) Alright so we got a bunch of numbers...

When one looks at the diagram neutron energy vs. probability of fission \sigma_f (measured in barns) there is a zone of resonance, characterized by peaks and valleys on the function \sigma_f. Why doesn't conventional nuclear power plants works in this zone, instead of using a moderator to slow...

so my problem deals with resonance in standing waves if you have a standing wave in a long pipe of length 2.90m and that is closed on the left end and open on the right end and the graph of it is as below, with x-axis the position along pipe and y-axis vertical air displacement...

Hello forum. I'm in abit of a mess. My high school physics class is in the process or doing individual investigations into an aspect of physics we are slightly familar with. I had planned out an experiment to do with sound, but last minute i was told another person was doing something...

hi this is not physics homework I really need to find out the natural frequency of a window size glass so that I can brake it with a couple of speakers. this is not a prank joke either. I need a practical way to find it help please. So far all i know is that the frequency is low by hitting it...

This isn't really a homework question. I'm just trying to figure things out for myself about resonance in a circuit that they haven't taught us yet. Say you have a circuit Rp || L || C and you have a sine source and some load connected to it call it Re and you want to mesaure the gain. Vi...

What is the resonance frequency expression for a parallel RLC circuit? I know that for a series RLC circuit, it is: w=\frac{1}{\sqrt{LC}} Is it the same for a parallel RLC circuit? I remember reading somewhere that it was not exactly the same, although it approaches the series RLC...
