Problem 1: Light with a
wavelength of λ = 635 nm is incident
on a single slit of
width w = 3.25 micrometers. A screen
is located L = 0.75 m behind the slit
and an interference pattern has formed on it.
What is the distance between the central bright spot and the
first dark fringe, D, in meters?
Problem 2: A red laser
(λ = 574 nm) is incident on a diffraction
grating that has n = 2100 lines per
cm.
Part (a) What is the angle, in radians,
that the first order maximum
makes, θ1?
Part (b) What is the angle of the fourth
order maximum, θ4, in radians?
