Wave parts

Multiple Select

Which of these words are parts of waves or wave behaviour? Tick all the correct ones!

• Wavelength

• Amplitude

• Frequency

• Bombast

• Reflection

Two main types of waves

• The energy of the wave always moves forward

• In transverse waves, the particles move up and down as the wave energy passes

• In longitudinal waves, the particles vibrate back and forth as the wave energy passes

Multiple Choice

Which of these is a longitudinal wave?

• Light

• Sound

• Earthquakes

Multiple Choice

Which of these is a transverse wave?

• Light

• Sound

• Fire

Key terms

• Wavelength is the length of one complete wave

• Amplitude is the height of the wave

• Antinodes are the places where the particles have moved a lot

• Nodes are the places where the particles haven't moved

Multiple Choice

What is frequency?

• The number of waves per second

• The time for one complete wave

• The length of one complete wave

Multiple Choice

What is wavelength?

• The height of a wave above or below equilibrium

• The length of one complete wave

• How many waves there are per second

Frequency and amplitude

• In sound waves, amplitude tells you the volume

• In light waves, amplitude tells you the brightness or intensity

• In sound waves, frequency tells you the pitch

• In light waves, frequency tells you the colour

Multiple Choice

If a sound wave has a high frequency, it also has a short wavelength

• True

• False

Multiple Choice

Only light waves can have large amplitudes

• True

• False

Multiple Choice

Sound waves with small amplitudes will be quiet

• True

• False

Multiple Choice

Light waves with low frequency will be red, as that has the longest wavelength

• True

• False

Wave behaviour

• Reflection is when a wave bounces off a boundary, like a mirror

• Refraction is when a wave bends as it passes through a boundary, like into water

Multiple Choice

To get a good reflection, a surface should be...

• Sparkly

• Rough

• Smooth

• Metal

Multiple Choice

A surface, like a shop window, can both reflect and refract light

• True

• False

Multiple Choice

Only light waves can reflect and refract

• True

• False
