Question

the phase difference between two points on a progressive wave is 7 pi/4.what will be corresponding path difference ​

Answer 1

Hey dear,

● Answer -
x = 7λ/8

● Path difference & phase difference -
- Path difference is the difference in path traversed by the two waves.
- Phase difference is the difference between some reference point in 2 waves.

● Explaination -
# Given -
Φ = 7π/4

# Solution -
Let λ be supposed wavelength of wave.

Path difference is given by formula -
x = λΦ / 2π
x = λ × (7π/4) / (2π)
x = 7λ/8

Therefore, path difference for given waves is 7λ/8.
