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
Give the right answer

Answer 1

Answer:

k = 2pie/lamda

lambda = 6.28/40

wavelength = 15.7cm

w = 5

2pie/T = 5

T = 1.25

n= 1/T
