Find the total number of bright spots

Reference no: EM13675761

Light of wavelength 631 nanometer passes through a diffraction grating having 360 lines/mm.

A. Find the total number of bright spots (indicating complete constructive interference) that will occur on a large distant screen? Answer this question without finding the angles. (Hint: What is the largest that sinθ can be? What does this imply for the largest value of m?)

B. Find the angle of the bright spot farthest from the center?
