Question

What is the ratio of phase difference and path difference?
​

Answer 1

Δx is the path difference between the two waves. ΔΦ is the phase difference between two waves.

...

Phase Difference And Path Difference Equation.

Formula Unit

Path Difference \Delta x=\frac{\lambda }{2\pi }\Delta \phi meter

Answer 2

Answer:

phase difference be α and path difference be x

then ,

α= x/λ ×2π

a/x =2π/λ
