Question

1. what is the amplitude?

the distance from the center of the wave to the crest or the trough.
the highest point in the wave
the lowest point in the wave
the distance between the two crests

Explanation:

Amplitude is defined as the maximum displacement from the equilibrium position (center of the wave) to either the crest (highest point) or the trough (lowest point) of a wave.

• The second option describes the crest.
• The third option describes the trough.
• The fourth option describes the wavelength (distance between two consecutive crests).

Answer:

the distance from the center of the wave to the crest or the trough.
