part 1: a spectrometer uses a grating with 11600 lines/ cm. Find the angle at which red light, 632.3 nm, has the first-order bright band. Answer in units of degrees.
part 2: find the angle at which blue light, 419 nm, has the first-order bright band. Answer in units of degrees.
Homework Answers
S = 1 x 10^7/11600 = 862.07 nm
A)
Theta_red = arcsin (632.3/862.07) = 47.18 degree
B)
Theta_blue = arcsin (419/862.07) = 29.08 degree

A diffraction grating with 4000 lines/cm is illuminated by light from the sun. The solar spectrum is spread out on a white wall across the room. (a) At what angle from the center line does blue light (400 nm) appear? (b) At what angle from the center line does red light (650 nm) appear? I know the formula that needs to be used is theta = m*wavelength/d but for the red light is sin theta = m*wavelength/d Thanks!
