Two light sources have intensity of light as Io . What is the resultant intensity at a point where the two light waves have a phase difference of π/3? |
|
Answer» Let the intensities be Io The resultant intensity is, I = 4Io cos2 (φ/2) Resultant intensity when, ϕ = π/ 3, is I = 4Io cos2 (π / 6) I = 4Io (√3 / 2)2 =3Io |
