What is the width of a single slit through which 520 nm green light passes to form a first diffraction minimum at an angle of 20.0∘?
Solution)
Given,
Wavelength, λ = 520 x 10^-9 m
For first diffraction minimum, we know
sin θ = λ / a
Width of slit, a=?
So, sin20=(520*10^-9 m)/a
Width, a= 1.52*10^-6 m
