An individual looks through a microscope while completely engaging their eye muscles, forming the final picture at their near point. If this person decides to relax their eyes, in which direction will they need to shift the object in relation to the objective? It's worth noting that they want the final picture to be in focus.

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.
