Suppose that you have a reflection diffraction grating with 135lines per millimeter. Light from a sodium lamp passes through thegrating and is diffracted onto a distant screen
a)Two visible lines in the sodium spectrum have wavelengths 498nmand 569 nm. What is the angular separation of the first maxima ofthese spectral lines generated by this diffraction grating?
Express your answer in degrees to two significant figures
b)How wide does this grating need to be to allow you to resolve thetwo lines 589.00nm and 589.59nm nanometers, which are a well knownpair of lines for sodium, in the second order ()?
Express your answer in millimeters to two significantfigures.
