1.       What is the wavelength of a light ray with frequency 5.09 × 1014 hertz as it travels through Lucite?

2.       A ray of light (f = 5.09 × 1014 Hz) is incident on the boundary between air and an unknown material X at an angle of incidence of 55°. The absolute index of refraction of material X is 1.66.

                     a.         Draw a ray diagram to represent the information given above.

                     b.         Identify a substance of which material X may be composed.

                     c.         Determine the speed of this ray of light in material X.

                     d.         Calculate the angle of refraction of the ray of light in material X.

3.       What is the speed of a ray of light (f = 5.09 × 1014 hertz) traveling through a block of sodium chloride?

4.       A ray of monochromatic light of frequency 5.09 × 1014 hertz is traveling from water into medium X. The angle of incidence in water is 45° and the angle of refraction in medium X is 29°.

                    a.         Draw a ray diagram representing this information.

                    b.         Calculate the absolute index of refraction of medium X.

5.      A ray of monochromatic light with a frequency of 5.09 × 1014 hertz is transmitted through four different media: corn oil, ethyl alcohol, flint glass, and water. Rank the four media from the one through which the light travels at the slowest speed to the one through which the light travels at the fastest speed.
