1
Q

What do waves transfer?

A

Only energy in the direction they are travelling.

Not matter.

2
Q

Define Amplitude.

A

The maximum displacement from the wave’s undisturbed position. (Height in m).

3
Q

Define wavelength.

A

Distance between the same point on 2 adjacent waves. (m).

4
Q

Define wave frequency.

A

The number of complete waves passing through a point per second.

5
Q

Describe oscillations for longitudinal waves.

A

The oscillations are perpendicular to the direction of energy transfer.

6
Q

Describe oscillations for transverse waves.

A

The oscillations are perpendicular to the direction of energy transfer.

7
Q

Give 3 examples of transverse waves.

A

Most waves:

  1. Light
  2. Water
  3. Seismic S waves.
8
Q

Give 3 examples of longitudinal waves.

A
  1. Sound
  2. Slinky
  3. Seismic P waves.
9
Q

Give the formula that links wavelength, frequency and speed.

A

Speed = frequency x wavelength
