Light of wavelength 631 nm passes through a diffraction grating having 485 lines/mm
1.) What is the total number of bright spots (indicating complete constructive interference) that will occur on a large distant screen? Solve this problem without finding the angles. (Hint: What is the largest that sinθ can be? What does this imply for the largest value of m?)
Express your answer as an integer.
2.) What is the angle of the bright spot farthest from the center?

A thin beam of laser light of wavelength 514 nm passes through a diffraction grating having 3952 lines/cm. The resulting pattern is viewed on a distant curved screen that can show all bright fringes up to and including ?90.0? from the central spot. If the experiment were performed with all of the apparatus under water (which has an index of refraction of 1.33), what would be the TOTAL number of bright spots that would show up on the screen?
