I'm getting the wrong answer, here's what I got so far:

dsin???? = nλ

λ = 700nm = 700 x 10^-9m

n = 1

d = .01m / 6000 lines = 1.67 x 10 ^-6m

???? = sin^-1[(nλ)/d] = sin^-1[(1 x 700 x 10^-9) / (1.67 x 10^-6)] = 24.78

Length on screen for first order: (1)tan(24.78) = .46m

.46m x 2 = .92m

V 1. White light with wavelengths between 400 nm and 700 um falls on a diffraction grating with 6000 lines/cm. A screen is 1.0 m from the grating. How wide does the screen
have to be so that the entire HF] and m=-1 orders appear on it. You cannot use the small
angle approximation for this problem.
