Question
Two narrow parallel slits (separated by the distance d = 0.9 mm) are illuminated by monochromatic light with lambda = 550 nm. The two slits create a diffraction pattern of bright and dark spots. Find the smallest angle theta1 (in degrees) at which the rays from the two slits create a bright spot.

Answer:
The smallest angle is
Explanation:
From the question we are told that
The distance of separation is d = 0.9 mm
The wavelength is
General the location of the interference fringes is mathematically represented by
m is the order of the fringe
Now the smallest angle at which both ray create a bright spot would be when
m= 1
Substituting values
