Could someone please explain how I do this or provide a link explaining how. I am very confused.

1)
a) Name 2 properties of waves that change if the wave changes media.
b) Name a property that does NOT change when it changes media.

2) If the wavelength of a wave increases when the wave changes media, what happens to the frequency?

3) Name 2 ways to increase the energy of a wave.

4) A 2.00m long string is vibrated 5.00 times every second to create a standing wave with 2 antinodes.
a) What is the speed of the waves creating the standing wave?
b) What is the fundamental frequency of the string?
c) What frequency will produce resonance with 3 antinodes?

5) What is the source of all waves?

7) Name the 3 behaviors of all waves and give an example of that behavior for sound.

8) What is a standing wave the result of?
