A double slit system contains two slits that are separated by a distance of 0,25 mm and each slit
has a width of 0.05 mm. Green light of wavelength 510 nm shines on the double slit, and an interference pattern
appears on a screen that is 2.4 meters awav.
The central bright spot of the pattern is labeled y =0 on the screen.
(1 nm =10-9 m)
What is the angle (in degrees to the 3rd bright spot away from the central bright?
b) The double-slit bright spots are counted form the center with the center bright being m
=0 What is the
m. value for the first bright spot that is missing because it overlap
S with the position of the single-slit dark
spot pattern?
c) At what distance from the center is the first missing bright spot?
