Question

The vertical displacement of particles in a string (when a wave is propagating through it) is given by y = (0.02) sin[(10wt + 8wx)], where everything is measured in standard units, meters and seconds. What is the wavelength of the wave?

A. 2 m
B. 3.5 m
C. 4 m
D. 0.25 m
Expert Solution
Step 1 Introduction:

Given:

Vertical displacement, y=0.02sin 10wt+8wx

Step 2 Explanation:

The wave equation, y=Asinkx-wt

So,

Amplitude, A=0.02m

k=8w
