Understanding Waves and Their Properties

What is a wave?

• A solid object that transfers matter

• A vibration that transfers energy without transferring matter

• A liquid that moves from place to place

• A gas that remains stationary

What is the medium in wave terminology?

• The energy source of the wave

• The substance through which some waves must travel

• The speed at which a wave travels

• The height of a wave

Which type of waves need a medium to travel?

• Electromagnetic waves

• Sound waves

• Light waves

• Microwaves

What happens to the medium when waves travel through it?

• It remains completely still

• It vibrates as the waves pass through

• It changes into a different state of matter

• It disappears

Which types of waves do not need a medium to travel?

• Sound waves

• Seismic waves

• Electromagnetic waves

• Water waves

What is the amplitude of a wave?

• The distance between two crests

• The maximum disturbance from its undisturbed position

• The speed of the wave

• The number of waves passing a point per second

How is wavelength defined?

• The height of a wave

• The distance from the crest to the trough

• The distance between a point on one wave and the same point on the next wave

• The speed of the wave

What is the frequency of a wave?

• The height of the wave

• The distance between two crests

• The number of waves produced by a source each second

• The speed of the wave

What is the unit of frequency?

• Metres (m)

• Seconds (s)

• Hertz (Hz)

• Joules (J)

What is the formula for wave speed?

• Wave speed = Amplitude x Wavelength

• Wave speed = Frequency x Wavelength

• Wave speed = Frequency / Amplitude

• Wave speed = Wavelength / Frequency
