A teacher demonstrated how the frequency of a wave on a string affects the box
wavelength of the wave.
Figure 1 shows the equipment used.
Figure 1
The frequency of the signal generator is adjusted so that the wave shown
in Figure 1 is seen.
At this frequency the string vibrates between the two positions shown in Figure 1.
0 1 . 1 Describe a method the teacher could use to investigate how the
frequency of the wave affects the wavelength. Use the Physics Equations Sheet to answer questions 01.2 and 01.3. box
0 1 . 2 Which equation links frequency (f), wavelength (λ) and wave speed (v)?
[1 mark]
Tick () one box.
f = λ × v
λ = f × v
v = f × λ
0 1 . 3 The wave on the string has a frequency of 45.0 Hz.
The wave speed is 35.1 m/s.
Calculate the wavelength of the wave.

outside the
0 2 box Figure 2 shows an Olympic gymnast performing a floor routine.
Figure 2
The floor contains springs.
When the gymnast lands on the floor, a force compresses the springs in the floor.
0 2 . 1 When a spring is compressed, the elastic potential energy of the spring increases.
Explain why compressing the springs in the floor helps the gymnast to jump higher.
Use ideas about energy in your answer.
