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.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
