Homework Statement
A monochromatic plane wave is normally incident on a diffraction grating with 105 lines/m. For what visible wavelengths would this grating produce a maximum at 11°.
Homework Equations
d*sinθ = m*λ
The Attempt at a Solution
d = 1 x 10-5 m
I don't get how to actually solve it because i don't know what the m for this situation would be.
