What is the arrangement of molecules in a longitudinal wave that is spread out?

• A) Rarefaction

• B) Compression

• C) Diffusion

• D) Dispersion

What type of waves travel as longitudinal waves?

• An example is sound waves.

• Light waves

• Radio waves

• X-rays

Calculate the wave frequency based on the given question.

The speed of the wave is 15 m/s and the wave length is 30m

• 15m/s x 30m = 45Hz

• 30m /15m/s =2m

• 15m/s /30m = .5Hz
