a.

Use the Figure to determine the amplitude of the wave.

[1]
b.

Use the Figure to determine the period of the wave.

[1]
c.

Calculate the frequency of the wave.

Use the equation

frequency=1period\text{frequency} = \dfrac{1}{\text{period}}frequency=period1​

[2]
d.

The wavelength of the wave is 6.0 cm.

Calculate the speed of the wave in m/s\text{m/s}m/s.

[3]
e.

A student says:

'The distance between two crests on the Figure is the wavelength of the wave.'

Explain why the student is wrong.
