Problem 3: A light with
wavelength λ = 505 nm falls on a pair
of closely separated slits. The first dark fringe of the
interference pattern is at an
angle θ = 6.75 degrees from the
central maximum.
Express the separation between the slits in terms
of θ and λ. Solve for the
numerical value of d in mm.
Problem 4: Consider
a 460 nm wavelength blue light falling on a pair of slits
separated by 0.055 mm.
At what angle (in degrees) is the first-order maximum for the
blue light?
Problem 5: Suppose a two-slit
interference pattern from 605 nm orange light has its
first maximum at an angle of 1.76°. This is a double-slit
system already in problem formulation.
What is the separation between two slits for the orange light in
meters?
