What is the horizontal distance between two waves, measured at a common point (crest to crest or trough to trough), called?
frequency
linear
absorption
wavelength
Seismic waves are just one type of wave. Sound and light also travel in waves. Every wave has a high point called a crest and a low point called a trough . The height of a wave from the center line to its crest is its amplitude . The horizontal distance between waves from crest to crest (or trough to trough) is its wavelength ( Figure below ).
