Which of the following is not caused by atmospheric refraction of light ?
Sun appearing red at sunset
Twinkling of stars at night
Sun appearing higher in the sky than it actually is
Sun becoming visible two or three minutes before actual sunrise
Sun appearing higher in the sky than it actually is
The twinkling of stars and variation in size of the Sun are due to atmospheric refraction of light. Besides, refraction is also responsible for the sun to look during sunset and sunrise. It is also responsible for the sun becoming two or three minutes before actual sunrise. The sun appears higher or lower in the sky due to the changing position of the Earth relative to the Sun.
