Homework Statement
Two slits are separated by 0.320 mm. A beam of 500-nm light strikes the slits, producing an interference pattern. Determine the number of maxima observed in the angular range -30 degrees < theta < 30 degrees.
Homework Equations
d*sin(theta) = m*(lambda)
The Attempt at a Solution
(.32)sin(30)/.0005mm = m
m=320
so there are 320 maxima in 30 degrees. and thus 640 in this total range. is that right?
