## Diffraction Grating
A diffraction grating splits light into its component wavelengths at specific angles.
### Formula
**d * sin(theta) = m * lambda**
where d is the slit spacing, m is the diffraction order (1, 2, 3, ...), and lambda is the wavelength. The slit spacing d = 1/(lines per unit length).

Ejemplo Resuelto
First-order diffraction of 550 nm light through a 600 lines/mm grating (d = 1667 nm).
- d * sin(theta) = m * lambda
- 1667 * sin(theta) = 1 * 550
- sin(theta) = 550/1667 = 0.3299
- theta = 19.26°
