To determine

The correct option for the statement “The properties of lenses depends mainly on”.

Answer to Problem 3RAT

The correct option for the statement “The properties of lenses depends mainly on” is option (b).

Explanation of Solution

The phenomenon in which the light rays send back in the same medium after hitting the other material's surface is termed as reflection.

Refraction is the process in which a light-wave diverts its path when it enters from one material medium to another medium. This occurs due to variation in the refractive index, which affects the speed of light.

Dispersion can be defined in the simple layman language as splitting single light into several components of light.

Lenses are generally made up of glass that has a greater refractive index than air. When light-wave enters from air to glass, there is a reduction of speed due to which light wave diverted toward the normal hence refraction is the main property shown by the lenses.

Conclusion:

herefore, the correct option for the statement “The properties of lenses depends mainly on” is option (b).
