Equation for finding path difference between two waves in single slit interference
path difference = 0.5bsinθ
b = width of aperture
Equation for finding the angle of minimum points in single slit interference
bsinθ = nλ, n = 1, 2, 3,…
How does the angular width of the central maximums in single slit diffraction change as the slit width increases?
As slit width increases angular width decreases
