Homework Statement
Do waves travel faster in dense or less dense mediums?
As a wave moves from a less dense to a denser medium at a boundary end what properties change? (Wavelength, speed, frequency, amplitude...)
If waves travel faster in solids then why do we hear better through air, and if we listen in water or solid it's deep and slow.
Homework Equations
-none- it's a conceptional question
But maybe these are helpful:
Frequency=1/ period
Speed=frequency*wavelength
The Attempt at a Solution
For the first question I previously thought that waves travel faster in more dense mediums, but I found this link. In the section about
"Transmission of a Pulse Across a Boundary from Less to More Dense"
It says the opposite.
So which is true ?
My second question is a result of the first and also refers to the same section in the link above. Why did the denser medium have a smaller amplitude and so did there reflected wave.
For my last question I don't have an idea on what might be the answer.Thank you for your help in helping me understand this confusing topic, because I am currently really frustrated with y lack of understanding the topic for many weeks now.
