1
Q

Waves transfer ______ without transferring _______

A

Waves transfer energy without transferring matter

2
Q

What are the two types of waves?

A

Mechanical and electromagnetic waves

3
Q

Give 2 examples of mechanical waves

A

Sound, water, seismic waves and those on springs and ropes

4
Q

What are transverse waves?

A

Waves that oscillate (vibrate) perpendicular to the direction in which the waves are moving

5
Q

What is a longitudinal wave?

A

Waves that travel parallel to the direction in which the energy is moving

6
Q

What is an example of a longitudinal wave?

A

Sound waves

7
Q

What is is an example of a transverse wave?

A

Light waves

8
Q

What does mechanical waves need to exist?

A

A medium to travel through

9
Q

What is the amplitude of a wave?

A

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

10
Q

What is the wavelength of a wave?

A

The distance from a point on the wave to the equivalent point on the adjacent wave

11
Q

What is an increase in the amplitude of a wave the result of?

A

The wave carrying more energy

12
Q

What is the frequency of a wave?

A

The amount of waves passing a fixed point every second

13
Q

What is the equation linking frequency and 1?

A

Period, s = 1/frequency, Hz

14
Q

What is the speed of a wave?

A

The distance travelled by each wave every second through a medium. Energy is transferred by the waves at this speed

15
Q

What is the equation linking wave speed and wavelength?

A

Wave speed, m/s = Frequency, Hz x Wavelength, m
