Question

The equation of progressive wave is y=5sin2(100t-x) where x and y are in metres and t is second. Calculate: (a) amplitude and angular frequency (b) period and angular wave number (c) wavelength and the speed of the wave

Answer 1

Explanation:

a)

amplitude A=5m

angular frequency w=100 radians/s or hZ

b)

time period=2.pie/w

T=pie/50 s

angular wave number k=1

c)

wave length λ=2.pie/k

λ=2.pie

speed of wave=w/k

v=100m/s
