Phys 375 HW 6
Fall 2010
Due 15 November, 2010
1.
A single slit in an opaque screen 0.10 mm wide is illuminated (in air) by plane waves
from a krypton ion laser (
0
= 461.9 nm).
If the observing screen is 1.0 m away,
determine whether or not the resulting diffraction pattern will be of the farfield variety
and then compute the angular width of the central maximum.
2.
What is the relative irradiance of the subsidiary maxima in a threeslit Fraunhofer
