Question 41
1 mark · Easy
Answer and see the solution →State whether sound waves in air are transverse or longitudinal.
Question 42
2 marks · Easy
Answer and see the solution →A teacher produces waves on a stretched spring. The frequency is 2 Hz and the time period is 0.5 seconds.
(a)[1 mark]State the equation that links frequency and time period.
(b)[1 mark]Show, using the values above, that the relationship between frequency and time period is correct.
Question 43
1 mark · Easy
Answer and see the solution →Explain how you can tell whether a wave is transverse or longitudinal by observing the movement of particles in the medium.
Question 44
1 mark · Normal
Answer and check →Which statement correctly describes the motion of a particle in a transverse wave?
- A.It vibrates at right angles to the direction the wave is travelling.
- B.It vibrates along the same direction as the wave is travelling.
- C.It moves in circles as the wave passes.
- D.It stays motionless while the wave passes.
Question 45
3 marks · Normal
Answer and see the solution →A student is investigating waves along a stretched rope. She creates 12 complete waves in 3 seconds.
(a)[1 mark]Calculate the frequency of the waves.
(b)[1 mark]State the unit for frequency.
(c)[1 mark]Explain what is meant by the ‘frequency’ of a wave.
Question 46
2 marks · Normal
Answer and see the solution →State what is meant by the time period of a wave and explain how it relates to frequency, including the correct formula.
Question 47
3 marks · Normal
Answer and see the solution →Explain, with reference to energy transfer, how a wave can move along a spring without any part of the spring being carried along with the wave.
Question 48
3 marks · Normal
Answer and see the solution →Describe one example each of a transverse wave and a longitudinal wave, and for each, state clearly how the particles vibrate compared to the direction of wave travel.
Question 49
3 marks · Normal
Answer and see the solution →A wave has a time period of 0.02 seconds. Calculate its frequency.
Question 50
4 marks · Normal
Answer and see the solution →A student makes waves on the surface of a pool by repeatedly dipping her finger up and down in the water.
(a)[1 mark]State what is meant by a transverse wave.
(b)[2 marks]Describe, with reference to this situation, how the direction of vibration of the water relates to the direction in which the wave moves.
(c)[1 mark]Name another example of a transverse wave (other than water waves).
