A student is asked to measure the speed of waves in water and the speed of sound in a solid.
The student is given:
a ripple tank with a vibrating straight dipper, a lamp and a signal generator
a metal rod of length 1.00 m and a hammer
a metre rule, a stopwatch and a phone with a frequency app.
Explain how the student should use this equipment to determine the speed of the water waves and the speed of sound in the metal rod.
In your answer, explain why the equipment chosen for each measurement is suitable.
