State the diffraction grating equation for normal incidence.

How do you find grating spacing from line density \(n_L\)?

A grating has \(500\,\mathrm{lines\,mm^{-1}}\). Find \(d\).

A grating has \(600\,\mathrm{lines\,mm^{-1}}\). Find \(d\).

Using \(d=1.67\times10^{-6}\,\mathrm{m}\) and \(\lambda=632.8\,\mathrm{nm}\), find the first-order angle.

For the grating in question 5, find the second-order angle.

What condition limits the maximum possible grating order?

For \(d=1.67\times10^{-6}\,\mathrm{m}\) and \(\lambda=632.8\,\mathrm{nm}\), find the largest possible order.

Why are higher diffraction orders more spread out for a given grating?

If grating line density is increased, what happens to first-order diffraction angle for a fixed wavelength?

State the resolving power of a diffraction grating.

A grating has \(N=7200\) illuminated lines in first order. Estimate the resolving power.

A first-order grating measurement uses \(\lambda=600\,\mathrm{nm}\) and \(N=6000\) illuminated lines. Find \(\Delta\lambda_{\min}\).

A grating has \(600\,\mathrm{lines\,mm^{-1}}\) illuminated over \(12.0\,\mathrm{mm}\). Find the number of illuminated lines.

Using \(N=7200\), \(m=1\), and \(\lambda=632.8\,\mathrm{nm}\), estimate the smallest resolvable wavelength difference.

What is the central maximum order for a diffraction grating at normal incidence?

A grating gives a first-order angle of \(20.0^\circ\) for \(500\,\mathrm{nm}\) light. Find \(d\).

For the grating in question 17, estimate the line density in \(\mathrm{lines\,mm^{-1}}\).
