what is the formula for finding angular dispersion of grating? is it the same as angular width?

Yes I can, m = 2.26 but I don't know what to do next !

But I don't have the grating separation

π/2

the problem doesn't include the value of θ

Homework Statement Yellow sodium light, which consists of two wavelengths, λ_1 =589.0 nm and λ_2 = 589.89 nm, falls on a 7500 lines/cm diffraction grating. Determine (a) the maximum order m that will be present for sodium light, (b) the width of grating necessary to resolve the sodium lines...

It's the last step I could get in a bigger problem and I really tried.

Homework Statement 1 ≤ μ (tan(θ)+1)/(tan(θ)-1) Homework EquationsThe Attempt at a Solution 1 - (tan(θ)-1)/(tan(θ)+1) ≤ μ[/B]

I really would like to thank you guys I got it. I was hesitating to post the question as I thought it was too obvious. Thanks again :smile:

I know it's Sin/Cos however, I don't know how he did it.

Homework Statement I want to know how he simplified this expression to tan (theta) Homework EquationsThe Attempt at a Solution

I have just finished classical mechanics in Serway textbook and after studying some claculus I want more in-depth textbook with quite simple explanation and good exercises.

I am a second year physics and I want to study CM in more depth than that of the general textbooks

Hey everybody! I am a physics junior in education college and I feel that I am not getting a good preparation in Physics and Mathematics. I have a basic understanding of Algebra, Calculus I and General Physics And I am totally free for THREE months period and I am ready to study for at least 12...
