General Wave Properties

Radio waves are received at a house at the bottom of a hill. The waves reach the house because the hill has caused them to be

• diffracted

• radiated

• reflected

• refracted

Which list contains only transverse waves?

• infra-red waves, light waves, sound waves

• infra-red waves, light waves, ultraviolet waves

• infra-red waves, sound waves, ultraviolet waves

• light waves, sound waves, ultraviolet waves

A water wave in a shallow tank passes through a gap in a barrier. What happens to the speed and what happens to the wavelength of the wave as it passes through the gap?

• Speed decreases, wavelength decreases

• Speed decreases, wavelength remains constant

• Speed remains constant, wavelength decreases

• Speed remains constant, wavelength remains constant

The diagrams show water waves that move more slowly after passing into shallow water. Which diagram shows what happens to the waves?

• 
• 
• 
• 

What is the number of wavefronts per second that pass a fixed point?

• the amplitude of the wave

• the frequency of the wave

• the speed of the wave

• the wavelength of the wave

The diagram shows a water wave in a ripple tank. Which line represents a wavefront?

• A

• B

• C

• D

The diagram shows a side view of a water wave at a particular time. The diagram is drawn full size. Which statement about the wave is correct?

• The wave is longitudinal and the frequency can be measured from the diagram.

• The wave is longitudinal and the wavelength can be measured from the diagram.

• The wave is transverse and the frequency can be measured from the diagram.

• The wave is transverse and the wavelength can be measured from the diagram.

The diagram represents a water wave. Which row shows the amplitude and the wavelength of the wave?

• amplitude (1m), wavelength (2m)

• amplitude (1m), wavelength (4m)

• amplitude (2m), wavelength (2m)

• amplitude (2m), wavelength (4m)

The diagram represents circular wavefronts coming from point S. The wavefronts strike a barrier and are reflected so that they appear to come from point S1. Which diagram shows the reflected wavefronts?

• 
• 
• 
• 

A water wave moves quickly in deep water. The wave now enters shallow water and its speed decreases. What happens to the frequency and wavelength of the wave?

• Frequency decreases, Wavelength decreases

• Frequency decreases, Wavelength does not change

• Frequency does not change, Wavelength decreases

• Frequency does not change, Wavelength does not change
