Refer to the image shown to answer the question. If a light ray is reflected off the shiny surface at 170 degrees, at what angle did the light ray first strike the surface?
Incident rays are shown at 10, 30, 50, and 70 degrees. The line at 90 degrees is labeled normal. Reflected rays are shown at 110, 130, 150 and 170 degrees.

70 degrees

170 degrees

10 degrees

110 degrees

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
