When a ray of light is incident at normal incidence, (at right angles), to ... When the ray is incident at any other angle, the ray changes direction as it refracts. The dotted line is the normal ...

the Dove prism acts as a retroreflector or a right-angle prism. The light exits parallel to the input light (independent of the incidence angle) and is inverted by 180°. In situations with limited ...

Plot a graph of angle of incidence, i in o on the y-axis against angle of refraction, r in o on the x-axis and draw the line of best fit. We can see from the graph that as the angle of incidence ...

Cube beamsplitters are produced by first coating the hypotenuse of a right-angle prism and then cementing this prism to ... Partial mirrors work at off-normal angles of incidence, reflecting only a ...
