Monochromatic light with wavelength 570nm passes through a circular aperture with diameter 7.00?m . The resulting diffraction pattern is observed on a screen that is 5.00m from the aperture.

What is the diameter of the Airy disk on the screen in cm?

Suppose that you have a reflection diffraction grating with n= 110 lines per millimeter. Light from a sodium lamp passes through the grating and is diffracted onto a distant screen.

How wide does this grating need to be to allow you to resolve the two lines 589.00 and 589.59 nanometers, which are a well known pair of lines for sodium, in the second order (m=2)?
