Question
Which of the following statements are true?
True False If a light beam is incident under an angle to the surface vector of a medium of a lower index of refraction, it continues under a larger angle.
True False Total internal reflection only occurs for light beams coming from inside an optically denser medium.
True False The index of refraction is the ratio of the vacuum speed of light to the speed inside the medium.
True False The index of refraction is independent of the wavelength of the light.
