Assertion: Just before setting, the sun may appear to be elliptical. This happens due to refraction.
Reason: Refraction of light ray through the atmosphere may cause different magnification in mutually perpendicular directions.
Reason: Refraction of light ray through the atmosphere may cause different magnification in mutually perpendicular directions.
View answer and explanation
Correct option: A
If both assertion and reason are true and the reason is the correct explanation of the assertion
The correct answer is A (If both assertion and reason are true and the reason is the correct explanation of the assertion) because atmospheric refraction causes the sun to appear elliptical due to differential magnification.
