  • A transverse harmonic wave on a string is described by where x and y are in cm and t in s. The positive direction of x is from left to right. What is the least distance between two successive crests in the wave ?

Q.15.8 (d) A transverse harmonic wave on a string is described by

 y(x,t)=3.0\; \sin (36\; t+0.018\; x+\pi /4)
 where x and y are in cm and t in s. The positive direction of x is from left to right.

(d) What is the least distance between two successive crests in the wave?

The difference between two consecutive crests is equal to the wavelength of the wave.

\\\lambda =\frac{2\pi }{k}\\ \lambda =\frac{2\pi\times 10^{-2} }{0.018}\\ \lambda =3.49\ m
