Label the parts of the transverse wave.

Amplitude:

Crest :

Trough:

Wavelength:

A transverse wave occillates perpenticular to the direction of energy transfer. A = Crest, B = trough, C = Amplitude, and D =  Wavelength.

Transverse Wave,

In this wave oscillates perpendicular to the energy transfer. For example, Electromagnetic wave.

Therefore, A = Crest, B = trough, C = Amplitude, and D =  Wavelength.

Amplitude: B

Crest: A

Trough: C:

Wavelength: D

Explanation:

The amplitude of the wave is defined as the distance from the equilibrium position of the wave to its crest or troughs; therefore,

Amplitude: B

The Crest of a wave is its highest point from its equilibrium position; therefore,

Crest: A

The trough of a wave is its lowest point measured from equilibrium position; therefore,

Trough: C

The wavelength of a wave is the distance between two identical points on a wave; therefore,

Wavelength: D.

50 inches should be the resultant vector
