## Homework Statement

## Homework Equations

slit width = a , slit seperation = b = d (at photo),

tanQ=h/L m.λ=b.sinQ

λ.b=sinQ

B=π.d.sinQ/λ

α=π.a.sinQ/λ

Iq=Imx(cosB)^2 x (sinα/α)^2//

## The Attempt at a Solution

My first move was to find intensity but I have no idea about the probability of finding one photon on the detector since It is not a point and It has own length.Should I think the detector as a point ? Location can be relevant with fringes but I'm not sure.
