1) A ray of light is incident on the surface of a block of clear ice at an angle of 35.0 degrees with the normal. Part of the light is reflected and part is refracted. Find the angle between the reflected and refracted angle ( Answer in degrees)
Monochromatic light ( = 630 nm) strikes a pair of slits at normal incidence, forming a double-slit interference pattern on a screen located 1.20 m from the slits. It shows the interference pattern observed on the screen. What is the slit separatio..
