T4 - Properties Of Waves

Question 1

What are the two types of waves?

Answer 1

1.Transverse
2. Longitudinal

Question 2

What is a transverse wave?

Answer 2

A wave for which the oscillations are perpendicular to the direction of energy transfer.

Question 3

What is a longitudinal wave?

Answer 3

A wave for which the oscillations are parallel to the direction of energy transfer.

Question 4

Give two examples of transverse waves.

Answer 4

1. Electromagnetic waves
2. Seismic s-waves

Question 5

Give two examples of longitudinal waves.

Answer 5

1. Sound waves
2. Seismic p-waves

Question 6

What are the two parts of a longitudinal wave called?

Answer 6

Compressions and rarefactions.

Question 7

What are the two parts of a transverse wave called?

Answer 7

Peaks and troughs.

Question 8

What is a wave’s amplitude?

Answer 8

The maximum displacement of a point on a wave from its undisturbed position.

Question 9

What is wavelength?

Answer 9

• The distance from a point on a wave to the same position on the adjacent wave
• Most commonly peak to peak or trough to trough

Question 10

What is the frequency of a wave?

Answer 10

The number of waves that pass a given point each second.

Question 11

What is meant by a frequency of 200Hz?

Answer 11

200 waves pass a given point each second.

Question 12

What is wave speed?

Answer 12

The speed at which energy is transferred through a medium.

Question 13

What does a wave transfer?

Answer 13

Energy

Question 14

State the equation used to calculate wave speed.

Answer 14

Wave Speed = Frequency × Wavelength
