Problem 6: Suppose the
first-order maximum for monochromatic light falling on a double
slit is at an angle of 7.5°.
Part (a) At what angle (in degrees)
is the second-order maximum?
Part (b) What is the angle (in
degrees) of the first minimum?
Problem 7: Light of
wavelength λ = 550 nm is incident upon
two thin slits that are separated by a
distance d = 25 μm. The light hits a
screen L = 1.3 m from the screen. It
is observed that at a point y = 3.1 mm
from the central maximum the intensity of the light
is I = 95 W/m2.
Part (a) Write an equation for the
phase shift between the light from the two slits at the observation
point in terms of the given variables.
Part (b) For the given data, what is
the phase shift, in radians, between the light from the two slits
at the observation point?
Part (c) What is the intensity of
the light at the two slits (I0) in watts per
square meter?
