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.

Q2.The lens is the transparent optical device that affects the focus of a light beam through refraction. Choose one type of the lens and give one application in our everyday lives and explain it (Minimum five lines).

The resolving power of a refracting telescope increases with the diameter of the spherical objective lens. In reality, it is impractical to increase the diameter of the objective lens beyond approximately 1 m. Why? a. The resultant sagging of the mirror will cause spherical aberration. O b. The resulting increase in light scattering from the surface of the objective lens will blur the image. c. If the objective lens is too large, it is difficult to keep it clean. d. The increasing size of the objective lens will cause chromatic aberration to grow worse than spherical aberration. O e. The spherical objective lens should be replaced by a paraboloidal objective lens beyond a 1-m diameter.
