Homework Statement
A heavy rope 3 m long is attached to the ceiling and allowed to hang freely. Let y = 0 denote the bottom end of the rope. To get started on this problem, imagine cutting the rope at an arbitrary value of y. Draw a free body diagram of each of the two pieces of rope to...

I'm trying to understand the detailed mechanics of a transverse wave in a rope. I base my ideas here on Crowell's textbook (see...
Hi all, i want to ask a simple question which is not so for me. Actually while studying transverse waves, a line is written:-"EACH TRANSVERSE WAVE HAS TWO POSSIBLE POLARISATION STATES". Can anybody tell me please which are those two possible polarisation states refer here (either up and down or...
Displacement of Transverse Waves HELP!
Homework Statement
At time t=0, the displacement of a transverse wave pulse is described by y=2/(x^(4) +1), with both x and y in cm. Write an expression for the wavefunction as a function of position x and time t if it is propagating in the positive x...
A sinusoidal wave is traveling on a string with speed 10.00 cm/s. The displacement of the particles of the string at x = 20 cm is found to vary with time according to the equation y = (5.0 cm) sin[16.0 - (8.0 s-1)t]. The linear density of the string is 7.0 g/cm.
(a) What is the frequency of the...
Homework Statement
Two transverse waves are on the same piece of string. The first has displacement y non-zero only for kx + wt between pi and 2pi, when it is equal to Asin(kx + wt). The second has y = Asin(kx - wt) for kx - wt between -2pi and -pi, and is zero otherwise. When t=0, the...
Pretty basic question, i think, it's either possible or it's not.
Physics practical using an ultrasound generator and receiver components (in separate circuits, with the the generator rigged up to signal generator, and the receiver connected to an oscilloscope to take readings from). For the...
hello all,
i am new to this forum and to physics itself. I am a high school student who has studied physics for about two weeks. Regardless of this, while studying a question arose. it is this;
according to the theory of superposition, two waves moving in opposite directions, one positive...

Homework Statement
Two transverse waves traveling on a string combine to a standing wave. The displacements for the traveling waves are Y1(x,t) =0.0160m sin(1.30m^-1x -2.50s^-1t + 0.30) and Y2(x,t) = 0.0160m sin(1.30m^-1x -2.50s^-1t +.070), respectively, where x is position along the string...
When two waves traveling in opposite direction say in a thread, superpose the shape of the thread becomes flat. Where is the energy stored in the thread now. When a single is travelling, we say energy is stored as potential energy. But here there is no displacement of the thread in the vertical...

A cowgirl ties one end of a 10.0-m-long rope to a fence post and pulls on the other end so the rope is stretched horizontally with a tension of 140 N. The mass of the rope is 0.800 kg.
a) What is the speed of transverse waves on the rope?
b) If the cowgirl moves the...
Electromagnetic wave are said to travel with velocity c, in vacuum and are also said to be a transverse wave. But consider this:
Let a positive charge Q be at point P of a three dimensional space.
Let this charge, at time t=0, begin an uniform circular motion with angular velocity OMEGA =...
A telephone cord is 4.00 m long and has a mass of 0.300 kg. A transverse wave pulse is produced by plucking one end of the taut cord. The pulse makes three trips down and back along the cord in 0.700 s. What is the tension in the cord?
ok, this problem seems very easy and straightforward...
