Question

As shown, suppose that for some point P on the screen r₁ = 5,002,248.5λ and r₂ = 5,002,251.5λ, where λ is the wavelength of the light. The interference at point P is
A. Constructive. B. Destructive. C. Something in between.

(b)
1. A plane wave is incident
on the double slit.
3. Constructive interference occurs
when r, and r, differ by a whole
number of wavelengths.
2. Waves spread out
m = 4
behind each slit.
The bright fringes
are labeled by the
integer m, starting
at the central
m=3
m=2
maximum.
