What is the speed of your image relative to you? m/sThe direction that a light wave bends once it enters the refracted medium depends on a. The index of refraction of the incident medium only. b. The indices of refraction of both the incident and refracted media. C. The angle of incidence of the incident light ray only. d. The index of refraction of the refracted medium, only.Rays of light coming from the sun (a very distant object) are near and parallel to the principal axis of a concave mirror. After reflecting from the mirror, where will the rays cross each other at a single point?
