    A ray of light traveling from water into barium glass strikes the surface at an angle of 300. Calculate the angle of refraction.

    2. Determine the index of refraction of a medium if the angle of incidence in air is 250 and the angle of refraction in the medium is 150.

    3. If the index of refraction of a medium is 1.50 and light travels from air in tot he medium where the angle of refraction is 180, calculate the angle of incidence.

    4. A ray of light traveling in air strikes the surface of Jell-O at an angle of 23º. Iff the light travels at 2.22 x 10(^8) m/s through the Jell-O:a) Calculate the index of refraction for Jell-O.b) Calculate the angle of refraction
