7P3.5 waves recap

Waves transfer...

• Energy

• Sound

• Matter

• Slinky

What type of wave is this?

• Transverse

• Longitudinal

Answer explanation

The movement of particles is perpendicular (at a right angle) to the movement of the wave

Which is an example of a transverse wave?

• Light

• Sound

Sound is an example of what type of wave?

• transverse

• longitudinal

Which type of wave can travel through a vacuum (empty space)?

• light

• sound

Answer explanation

Sounds are made by vibrating particles.

No particles = no sound!

This word means 'give out light'

• bulb

• emit

• reflect

What is being shown by the blue line?

• Amplitude

• Wavelength

Answer explanation

Wavelength = distance between two peaks or troughs of a wave

What does frequency mean?

• How long the wave is

• How slow the wave is

• How many waves pass by every second

The longer the wavelength...

• The lower the frequency

• The higher the frequency

Answer explanation

If a long and a short wave are travelling at the same speed, more of the short waves will go past every second.

Which is true about a high frequency wave?

• Low energy

• High energy
