(a) Explain what is meant by the natural frequency of vibration of a system.
(b) A block of metal is fixed to one end of a vertical spring. The other end of the spring is attached to an oscillator, as shown in [Figure 4.1].
The amplitude of oscillation of the oscillator is constant.
The variation of the amplitude x₀ of the oscillations of the block with frequency f of the oscillations is shown in [Figure 4.2].
(i) Name the effect shown in [Figure 4.2].
(ii) State and explain whether the block is undergoing damped oscillations.
(c) State one example in which the effect shown in [Figure 4.2] is useful.
