Hi. Can someone please show me how to do the following problem? Thank you.
"A diffraction grating has 2200 lines/cm. What is the angle between the first-order maxima for red light ( = 690 nm) and blue light ( = 410 nm)?"© BrainMass Inc. brainmass.com March 4, 2021, 6:20 pm ad1c9bdddf
The general Bragg diffraction condition is,
d(sin èm - sin èi) = m ë.
Consider normal incidence, èi = 0 d sin èm = m ë
where d is the grating spacing
2200 lines/cm ==> 1cm is divided ...
Solution with all necessary mathematical steps and explanations.
