(a(i))[2]
Determine the wavelength for the wave in the ripple tank.
(a(ii))[2]
Define what is meant by frequency.
(a(iii))[1]
Determine the wave frequency.
(a(iv))[2]
The wave generator is a wooden bar. Describe the way it is used to create the wave shown.
(a(v))[1]
Some water is removed from the ripple tank. The water is now less deep. No other alterations are made. State how the change in depth affects the wavelength and the speed of the wave.
(b(i))[2]
This experiment needs other apparatus in order to measure the speed of sound. Name two other pieces of apparatus that are needed.
(b(ii))[3]
Describe the method used to make all the measurements.
(b(iii))[2]
State typical values for the speed of sound in: (1) a liquid, (2) a solid.
