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 = and v =10 ms-1, then λ and f are given by
(a) λ = 2π x 10-2 m
(b) λ = 10-3 m
(c) f = 103/2π Hz
(d) f = 104 Hz
