FAQ (Frequently Asked Questions)

1. Explain Defects of Vision and How to Correct Them.

Ans. Myopia, hypermetropia, and presbyopia are three significant defects of vision. Myopia refers to nearsightedness due to which a person can see nearby objects. A person who has myopia cannot see far objects clearly. This defect could be resolved with the help of a concave lens. In hypermetropia, a person cannot see near objects clearly and is corrected by using a convex lens. In presbyopia, a person is difficult to see both nearby and far objects. It is treated with the use of bifocal lenses.

2. What is Atmospheric Refraction Phenomena?

Ans. The deflection of light in the atmosphere refers to the phenomena of atmospheric refraction. The change in the direction of propagation of radiation in traversing the atmosphere is known as atmospheric radiation. This refraction is due to light velocity through air. With the increased density, it decreases. It is responsible for various phenomena like delayed sunset, the twinkling of stars, advanced sunrise, and more. The concept of atmospheric refraction is crucial to understand other phenomena occurring in nature.
