Wave Properties Quiz

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.

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?

Which is a unit of wavelength?

• hertz

• metre

• metre per second

• second

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

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

Which row describes the temperature, and the direction of movement, of the air in the gap?

• cool, away from the heater

• cool, towards the heater

• warm, away from the heater

• warm, towards the heater

Which statement about the wave is correct?

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