Answer and see the solution →The diagram below shows two types of waves on springs.
(a)[2 marks]Wave A and Wave B on springs Label which wave (A or B) is transverse and which is longitudinal.
(b)[2 marks]Explain your answer referring to the movement of the coils relative to the direction of energy transfer.
Question 12

Question 17
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.

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 19
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 20
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.
