Question

What is a progressive wave? What is a plane progressive harmonic wave? Establish the

displacement relation for harmonic wave travelling along the positive direction of X-

axis​

Answer 1

Answer:

The equation of a plane progressive wave travelling along positive direction of x-axis is y=rsin[2πtT-2πxλ] where y= displacement of particle at (x,t),r= amplitude of vibratio of particle, T= time period of wave motion, λ= wavelength of wave ,x= starting distance of wave from the origin.
