Question

g. What happens if the ruled surface of the grating faces the collimator"
​

Answer 1

Answer:

When mounting the grating on the prism table, if the ruled surface of the grating is towards the collimator, two images are viewed in the telescope placed with its axis normal to that of the collimator. The two images are formed by reflection at the front and back surfaces of the grating.
