Given the light fixture on the picture. In this device you will be able to change the beam angle from 5 to 60 degrees. Assume an isometric distribution of the light on the illuminated surface. If the distance to the floor is 3 meters, what will be the beam angle that will produce an Illuminated surface Diameter of 2 meters?
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.
