Question

The equation of wave is given by y = 0.5sin(60t - 0.2pi * x) (8.1unlts) , then the wavelength of the wave is​

Answer 1

Answer:

wave length of wave is 10 meter

Explanation:

given wave

y=0.5sin(60t-0.2$\pi$x)

we know general wave equation

y=Asin (wt-kx)

compare these equation

we get

A=0.5

wt=60t

kx=0.2$\pi$x

ie k=0.2$\pi$

we know

k= 2$\pi$/λ

put this value in above equation

2$\pi$/λ=0.2$\pi$

solving it we get

λ=10 meter
