THIS IS FOR PHYSICS SBA. PLEASE BE MORE DETAILED.
QUESTION:
1) State two sources of error in this experiment.
2) If a diffraction grating of 6000 lines/mm is used, what happens to the pattern formed by the grating?
3)Why we measure the separation among two first order of maximum. What is the advantage of the procedure?
