Question 11
1 mark · Normal
Answer and see the solution →Write down the equation that links wave speed, frequency and wavelength.
Question 12
2 marks · Normal
Answer and see the solution →Describe what is meant by the frequency of a wave.
Question 13
2 marks · Normal
Answer and see the solution →A student uses a ripple tank to produce waves with a wavelength of 0.04 m. The tank's motor produces 25 waves every second. Calculate the speed of the water waves.
Question 14
2 marks · Normal
Answer and see the solution →A radio wave has a frequency of 6 × 10^8 Hz and travels at a speed of 3 × 10^8 m/s. Calculate its wavelength.
Question 15
3 marks · Normal
Answer and see the solution →A student states, 'If the frequency of water waves in a ripple tank is doubled, the speed of the waves will also double.'
Explain whether this statement is correct.
Question 16
2 marks · Normal
Answer and see the solution →Describe two observations that show how increasing the frequency of a ripple tank motor changes the pattern of waves seen.
