Q 1480680517.     A transverse sinusoidal wave of amplitude `a`, wavelength `lamda` and frequency `f` is travelling on a stretched string. The maximum speed at 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 `lambda` and `f` are given by :

(This question may have multiple correct answers)

A ` lambda = 2pi xx 10^(-2)` m
B ` lambda = 10^-3` m
C ` f = (10^3)/(2pi)` Hz
D ` f = 10^4` Hz

HINT

`v_(max) = a omega ` `v = f lambda`
