This is a high frequency wave. Which part of the wave is "B"

• crest/peak

• wavelength

• trough

Which wave has the longest wave length?

• top wave

• bottom wave

The amplitude of a wave is...

• The total distance a wave will travel through a medium

• The height of a wave from the origin to a crest or trough

• The height of a wave from crest to trough

• The horizontal distance between two crests or troughs of a wave
