(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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:

E_{1}= E_{0}sin(wt + π/4)

E_{2}= E_{0}sin(wt + Φ)

Find the possible values of Φ if we have destructive interference at the point P.

2. Relevant equations

3. 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.
