Question

Case study: Mirage in deserts

To a distant observer, the light appears to be coming from somewhere below the ground. The observer naturally assumes that light is being reflected from the ground, say, by a pool of water near the tall object. Such inverted images of distant tall objects cause an optical illusion to the observer. This phenomenon is called mirage. This type of mirage is especially common in hot deserts. Based on the above facts, answer the following question:

Which of the following phenomena is prominently involved in the formation of mirage in deserts?

Options

• Refraction, Total internal Reflection

• Dispersion and Refraction

• Dispersion and scattering of light

• Total internal Reflection and diffraction

Answer 1

Refraction, Total internal reflection
