Homework Statement
In Young's double-slit interference experiment with light of wavelength [tex]\lambda[/tex], two light waves come from the slits and are superposed at the point P on the screen. These waves have the following forms:
E1 = E0 sin(wt + π/4)
E2 = E0 sin(wt + Φ)
Find the possible values of Φ if we have destructive interference at the point P.
Homework Equations
The Attempt at a Solution
I attempted the problem two different ways and I had two different results.
Φ = 2kπ - π/4
Φ = 2kπ + 5π/4
Help me out please.
