Which of the following is an example of a transverse and a longitudinal wave?

• A

• B

• C

• D

The diagram shows a water wave in a ripple tank.

The wave has a speed of 12 cm/s at R. The wave crosses a boundary PQ where the distance between crests changes from 3.0 cm to 1.5 cm. What is the velocity of the wave at point S?

• A 3.0 cm/s

• B 6.0 cm/s

• C 12 cm/s

• D 24 cm/s

• A

• B

• C

• D

A ray of light is incident on one side of a rectangular glass block. Its path is plotted through the block and out through another side. Which path is not possible?

• A

• B

The sounds produced by two musical instruments are directed towards a microphone connected to an oscilloscope (cro). The waveforms produced on the screen are shown. The waveforms show that the sounds produced have a different property. What is the property?

• frequency

• speed

• timbre (quality)

• wavelength

The diagram shows a wave moving into shallower water. The wavelength of the waves is reduced because

• A. both the frequency and the speed decrease.

• B. both the frequency and the speed increase.

• C. only the frequency increases.

• D. only the speed decreases.
