Waves

Question 1

Medium

Answer 1

Any substance that a wave moves through

Question 2

Mechanical waves

Answer 2

Waves that transfer energy through matter are known as mechanical waves

Question 3

Crest

Answer 3

The highest point or peAk of a wave

Question 4

Longitudinal wave

Answer 4

A wave that travels in the same direction as the disturbance

Question 5

Transverse wave

Answer 5

A wave that moves itself crosswise as compared with the vertical motion of the medium

Question 6

Trough

Answer 6

Lowest point of a wave

Question 7

Amplitude

Answer 7

Amplitude for A transverse wave is he distance between a line through the middle of a wave and a crest or trough

Question 8

Wavelength

Answer 8

The distance from one wave crest to the very next crest

Question 9

Frequency

Answer 9

Often so frequency measures how often a wave occurs
