Waves

Question 1

Wave

Answer 1

A movement of particles of the medium is perpendicular to the direction of propagation of the wave

Question 2

Crest

Answer 2

The point at which the medium reaches maximum displacement

Question 3

Trough

Answer 3

The point of minimum displacement

Question 4

Wave length

Answer 4

The distance between two adjacent points that are in phase

Question 5

Period

Answer 5

Time (T) taken for one wave to pass a specific point

Question 6

Frequency

Answer 6

The amount of waves that will pass by in 1 second

Symbol(f)

Question 7

Longitudinal waves

Answer 7

A wave where the particles in the medium are more parallel to the direction of the movement on the wave

Question 8

Compression

Answer 8

A region in a longitudinal wave where the particles are closest together

Question 9

Rarefaction

Answer 9

A region in a longitudinal wave where the particles are furthest apart

Question 10

Amplitude

Answer 10

Max displacement of particles from rest

r

Question 11

Wave speed

Answer 11

Speed at which compression appears to move. It is equal to the product of the wavelength and frequency
