Unit 5 - Waves

What is an example of a transverse wave?

• Light

• Sound

• Water

• Seismic

What type of waves consist of compressions and rarefactions?

• Longitudinal waves

• Transverse waves

• Surface waves

• Electromagnetic waves

In which direction do vibrations occur in longitudinal waves?

• In the same direction as the direction of travel

• At right angles to the direction of travel

• Opposite to the direction of travel

• In a circular motion

What is an example of a longitudinal wave?

• Sound

• Light

• Water

• Seismic

What is the term for the distance from the equilibrium position to the maximum displacement?

• Amplitude

• Frequency

• Wavelength

• Time period

What is the term for a line joining points on a wave at the same point in their wave cycle?

• Wavefront

• Amplitude

• Frequency

• Wavelength

What is the term for the time taken for one complete wave to pass a fixed point?

• Time period

• Frequency

• Amplitude

• Wavelength

What happens to the observed frequency and wavelength when a wave source is moving relative to an observer?

• They change due to the Doppler effect

• They remain constant

• They double

• They halve

What happens to wavefronts due to the Doppler effect?

• They get bunched together or spaced apart

• They remain unchanged

• They become circular

• They disappear

What does the law of reflection state?

• Angle of incidence = angle of reflection

• Angle of incidence = angle of refraction

• Angle of incidence = angle of absorption

• Angle of incidence = angle of transmission
