Answer:
The shortest distance covered by the wave between the given points is .
Explanation:
The Phase velocity () of any wave can be written as
where ‘‘ is the angular velocity and ‘‘ is the wave number.
Also, if ‘‘ is the frequency of the wave, then
Given, , and the phase difference between two points is .
If the wave travels by the shortest distance of between these points, then we can write
[tex]\v_{p} = \dfrac{\omega}{k}[/tex]
