Homework Statement
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 ◦.
Homework Equations
sin(theta) = m([tex]\lambda[/tex] /d)
The Attempt at a Solution
theta = inverse sin [( 1 * 635 e-9 m) / 24.69 m} = 1.4735 e -6 degrees
