Atmospheric refraction of light
and its application
Answers
Answer:
Applications of Atmospheric Refraction.
The apparent random wavering or flickering of object seen through a turbulent stream of hot air rising above a fire or a radiator. Twinkling of stars. Advanced sunrise and delayed sunset. Apparent flattening of the sun's disc at sunrise and sunset.
Explanation:
The atmospheric refraction is defined as the phenomenon of refraction of light due to change in the refractive index at different level in atmosphere. Light gets refracted at different layers of atmosphere. ... The star light bends towards the normal, the apparent position is different from the actual position of star.
EXAMPLE: Twinkling of stars: Starlight undergoes refraction many times before reaching the earth. ... It occurs because there is a gradual increase in the refractive index from the atmosphere to the earth's surface.
