For example, if a light ray hits a surface with an angle of incidence of 45°, it will be reflected with an angle of reflection of 45°.

d) Explain what will happen to the ray of light as the angle of incidence is increased from 10° to 80° mentioning angles of reflection and refraction where appropriate. [5 marks] ...

The conventional laws, taught in physics classrooms worldwide, predict the angles of reflection and refraction based only on the incident (incoming) angle and the properties of the two media.

Light travels from A, reflects off the bottom surface and then travels to point B. Show that for the path of least time, the angle of incidence is equal to the angle of reflection.

As it finally backs away through the glass, light doubling its loss through angles of reflection, your image doubles the distance between you—always twice as far from the source as you are ...
