Applications Of Reflection Of Light

When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.

Sign Convention for Mirrors

A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.

Question

5. Given an octagonal mirror, rotating about its center. A ray of light is incident from the
left, along the horizontal. At the mirror position shown, the incident ray makes an angle
of zero degrees with the normal to the mirror surface and is reflected back on itself.
What range of angles will the reflected ray make with the horizontal, as the mirror
rotation proceeds in a clockwise manner until the ray hits the next mirror facet.

For an independent study project, you design an experiment to measure the speed of light. You propose to bounce laser light off a mirror that is 55.0 km due east and have it detected by a light sensor that is 123 m due south of the laser. The first problem is to orient the mirror so that the laser light reflects off the mirror and into the light sensor. (a) Determine the angle that the normal to the mirror should make with respect to due west. (b) Since you can read your protractor only so accurately, the mirror is slightly misaligned and the actual angle between the normal to the mirror and due west exceeds the desired amount by 0.005°. Determine how far south you need to move the light sensor in order to detect the reflected laser light. Additienel Meteriele
