Do all electromagnetic waves travel at the same speed? Yes - 300,000 km/s
The pitch of a sound wave depends on the sound waves..... Frequency
What kind of light waves can be separated into the various colors of the spectrum to form a rainbow? Visible Light
What type of waves need a medium to transfer energy? Sound waves
What is the apparent change in frequency due to the motion of the observer or the source called? Doppler Effect
Frequency is measured in what units? Hertz (Hz)
What do we call the highest part of a transverse wave? Crest
What do we call the lowest part of a transverse wave? Trough
