Question:
A grating 1.600 cm wide has exactly 12000 slits. The grating is used to resolve two nearly equal wavelengths in a light source: λa = 440.000 nm and λb = 440.936 nm.
(a) How many orders of the lines can be seen with the grating?
(b) What is the angular separation θb − θa between the lines in each order?
(c) Which order best resolves the two lines? Explain.
