Light has a wavelength of 396.3 nm and a frequency of 4.551 × 1014 Hz when traveling through a certain substance. What is the refraction index of this medium? Use 2.998 × 108 m/s for the speed of light in a vacuum.

If the index of refraction of glass for red light is 1.45, what is the speed of a light, the speed of a photon, in the glass?     The same as the speed it would have in a vacuum, that is the same as "c"     Faster than the speed it would have in a vacuum by the factor 1.45     Dependent on the energy or power in the light     Slower than the speed in vacuum by the factor 1/1.45

The speed of light is faster through a substance with an index of refraction of 1.2 versus a substance with an index of refraction of 1.3. True or False?

Edward and Calil do some experiments to determine the speed of light in a special transparent material. They determine the speed of light to be 0.23c. Edward shines a light thru the material. Determine the critical angle in degrees for the light ray if there is a chamber of air above the material. Please give your answer as a whole number. (c is the speed of light in vacuum)

The speed of light in a vacuum is 3.00 ´ 108 m/s. If the refractive index of a diamond is 2.42, what speed does light travel as it passes through a diamond?
