Question 1

A crest is a point on the wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle. A point on the wave is a trough if the displacement of the medium.

Answer 1

Crest

Question 2

Crest (physics) From Wikipedia, the free encyclopedia. A crest is the point on a wave with the maximum value or upward displacement within a cycle. A crest is a point on the wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle.

Answer 2

Trough

Question 3

A Time period (denoted by ‘T’ ) is the time needed for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the time period of the wave decreases. … The period of a pendulum is the time it takes from one side to the other and back.

Answer 3

Period

Question 4

the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.

Answer 4

Wavelength
