Answer 2

Hello again!

Wavelength and frequency always go together for waves. Wavelength is the distance between "waves," and frequency tells you how many cycles you have per time.
They both apply to these waves.

However, the speeds are very different.

Answer 3

Sound and light both have varying speeds depending on what they're traveling through, but light is much faster. This is the difference between the velocity of the flash of lightning and the sound of the accompanying thunder. If the storm is a ways away, the difference is very perceptible.
