The graph shows the variation with time of the displacement of two separate waves X and Y. Wave X has frequency f and amplitude A. What is the frequency and what is the amplitude of wave Y?

1. Afrequency ½ f, amplitude ½ A
2. Bfrequency ½ f, amplitude 2A
3. Cfrequency 2f, amplitude ½ A
4. Dfrequency 2f, amplitude 2A
