Question 1 Report
Which of the following may be used to explain a mirage? i. layers of air near the road surface have varying refractive indices in hot weather. ii. road surfaces sometimes become good reflectors in hot weathers. iii. light from the sky can be reflected upwards after coming close to the road surface.
Answer Details
A mirage is a naturally occurring optical phenomenon in which light rays are refracted, or bent, to produce a displaced image of distant objects or the sky. The answer to this question is "i and iii only."
A mirage is caused by the refraction of light in layers of air with varying temperatures. In hot weather, the air near the ground is hotter than the air above it, causing light to refract and bend upwards. This creates the appearance of an image or object that is not actually there. This explains option i.
Option ii, which states that road surfaces become good reflectors in hot weather, is not a factor in the formation of a mirage.
Option iii is also correct because light from the sky can be reflected upwards after coming close to the road surface, which can contribute to the formation of a mirage.
