Question:

Sunlight (visible wavelengths between 400 nm and 750 nm) shines through a diffraction grating. If the first order spectrum spreads to 45 degrees on each side of the bright central maximum, what is the spacing of the slits in the diffraction grating?

Diffraction of Light:

When light passes through a grating, a diffraction pattern is formed. Diffraction is defined as the bending of light when light encounters edges, slits, and gratings. Diffraction is useful in determining the properties of a material. This phenomenon happens since light also exhibits wave-like charactersistics.

Answer and Explanation:

To solve for the slit spacing, we can use the equation for diffraction, which is given by:

{eq}d\sin{A} = nL {/eq}

where:

  • d is the spacing
  • A is...
