Question

A simple harmonic progressive wave y=8Sin2π(0.1x-2t) where x&y in cm, t in second.Find velocity of wave.Also find phase different in degree between particle separate d by 2cm in X-direction at any instant.​

Answer 1

Answer:

w = 4πt

k = .2π

Velocity = w/k

v = 20cm/s

∆Phi/2π = ∆x/lemda

lemda = 2π/K

LEMDA = 10cm

put Value

∆phi = 2π/5 in radian

∆phi = 72°
