Question

A travelling wave is given by the equation y = 0.03 Sin (2.2 x - 3.5t) where y and x are in metres and t is in seconds. Find the amplitude, the wayelength, the frequency, the period and the speed of the wave.​

Answer 1

Amplitude 0.03m, wavelength 2.86m, frequency 0.57Hz, period 1.8s

Explanation:

The traveling wave is described with the following equation:

`y=Asin(kx-wt)`

y=0.03sin(2.2x−3.5t)

A=0.03m

λ=2π/k=2π/2.2≈2.86m

T=1/f≈1.8s
