(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

White light is spread out into its spectral

components by a diffraction grating.

If the grating has 2469 lines/cm, at what

angle does red light of wavelength 635 nm

appear in first order?

Answer in units of ◦.

2. Relevant equations

sin(theta) = m([tex]\lambda[/tex] /d)

3. The attempt at a solution

theta = inverse sin [( 1 * 635 e-9 m) / 24.69 m} = 1.4735 e -6 degrees
