Q15.11Multiple correct
A transverse harmonic wave on a string is described by y (x,t) = 3.0 sin (36t + 0.018x + π/4) where x and y are in cm and t is in s. The positive direction of x is from left to right.
- (a)The wave is travelling from right to left.
- (b)The speed of the wave is 20m/s.
- (c)Frequency of the wave is 5.7 Hz.
- (d)The least distance between two successive crests in the wave is 2.5 cm.
