A cork floats on the surface of a pond. Water waves travel across the pond at 0.60 m/s.
The waves have a frequency of 2.0 Hz and an amplitude of 4.0 cm.
Calculate the wavelength of the waves.
Calculate the total distance moved by the cork in 1.0 s.
Assume that the cork only moves up and down.
A student says:
'The cork moves at the same speed as the wave.'
Explain why the student is wrong.
The amplitude of the waves decreases to 2.0 cm. The frequency does not change.
State the effect on the speed and on the wavelength of the waves.
