A transverse sinusoidal wave of amplitude a, wavelength λ and frequency f is travelling on a stretched string. The maximum speed of any point on the string is V/10, where V is the speed of propagation of the wave. If a = 10–3 m and V = 10 ms–1, then λ and f are given by
(a) λ = 2π × 10–2 m
(b) λ = 10–3 m
(c) f = 103/2π Hz
(d) f = 104 Hz.
