1. The problem statement, all variables and given/known data
Monochromatic light with a frequency of 5.50 x 10^14 Hz is directed onto a diffraction grating ruled with 6000 lines/m. What is the distance between the third bright line and the fifth dark line of the interference pattern formed on a screen 2.50m from the grating?
2. Relevant equations
wave length = dx/nL
Answer: 0.0123m
3. The attempt at a solution
wave length = 5.454545454545455e-7
d = 1/6000 = 1.666666667e-4
x = ?
n = ?
L = 2.50m
I have an exam on this tomorrow and I can't even do simple questions like these. If somone can explain how i would solve this it would be great.
