Problem: In a two-slit interference pattern, the intensity at the peak of the central maximum is I0.(a) At a point in the pattern where the phase difference between the waves from the two slits is 62.0 degrees, what is the intensity? Give your answer as a fraction of I0. (I/I0 = ? )(b) What is the path difference for light with a wavelength of 473 nm from the two slits at a point where the phase angle is 62.0 degrees?

FREE Expert Solution

The intensity of a two-slit interference pattern is expressed as:

I=I0cos2(ϕ2)

The path difference between the waves from the two slits:

ϕ=2πλ(r2-r1)
