Light Blue Red
What is the angle between the first-order maxima for red light and blue light?
A diffraction grating has 2200 lines/cm. What is the angle between the first-order maxima for red light ( = 685 nm) and blue light ( = 410 nm)?
___ degrees
Line separation a = 0.01/2200 = 4.54545e-6 m.
θ = arcsin(m*λ/a) where m is order (=1) and λ is wavelength (see ref.).
θ1 = 0.1512763 rad, θ2 = 0.0903228 rad.
You can do the rest.
