The speed of light in any transparent medium is the same as the speed of light in a vacuum.
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 x 108 m/s. What is the ratio of its speed in water (n = 1.33) to its speed in a vacuum? Enter your answer as a percentage
