Hi BvU!
Alright, I was able to work on the problem in class- I was missing a vital equation that made the whole process really easy.
The equation should be D=m/(d)cosΘ
So if...
D=dispersion
m=2
d=2.094 micrometers
Θ=30 degrees
Then the equation reads...
D=(2)/(2.094cos(30))
D=1.10...
1. The problem statement
A diffraction grating has a slit separation of 2094.0 nm. What is the dispersion of the 2nd order lines at an angle of 30 degrees (in degrees per micrometer)?
Homework Equations
dsinΘ=mλ
y=(mDλ)/d
3. Attempt at a solution
I began by finding λ using the first...
