This question tests the understanding of basic atmospheric optics and astronomical phenomena. - Atmospheric Refraction: The bending of light as it passes through different layers of the atmosphere with varying densities and temperatures. - Apparent Twinkling: The apparent variation in the brightness and position of a star as its light is continuously bent by atmospheric turbulence.
Twinkling of stars is due to : - A) Due to diffraction of light rays entering Earth's atmosphere - B) Reflection of light from the moon - C) Difference of temperature between various layers of air of varying density - D) Passage of artificial satellites in front of the stars
