Question

A wave, propagation along a string, is described by the equation y(x,t)sin0.04 sin (40x -5t) in which the numerical constants are in their respective SI units.calculate the
(a).wavelength
(b). time period
(c).frequency of the Wave

Answer 1

Answer:

$wave \: length \: = \frac{2\pi}{k} \\ wave \: length \: = \frac{6.28}{40} \\ wave \: length \: = 1.57. \\ \\ w = \frac{2\pi}{t} \\ t = \frac{6.28}{5} \\ t = 1.25$

hope the answer will help you
