Wavelength Calculations

What is the amplitude of a wave?

• The distance between two crests

• The total length of the wave

• The height from the center to the crest

• The distance between the crest and the trough

How is the amplitude of a wave determined?

• Top value minus bottom value divided by two

• Height of the crest only

• Distance between two consecutive crests

• Length of one cycle
