Light from a 620 nm wavelength laser passes through a diffraction grating with 4000 lines/cm in vacuum. The resulting pattern is viewed on a far curved screen that can show all bright fringes with direction up to and including ±90.0° from the center point. (a) What is the TOTAL number of shiny bangs that will appear on the screen? (b) Now the system is immersed in a liquid and two more shiny fringes appear, one at the top and one at the bottom. What is the minimum refractive index of the liquid?
