Why can’t we see clearly through fog?
Advertisements
उत्तर
During fog, the light coming from an object is partly deflected by the particles of the fog and does not reach the eye of the observer. Thus, the objects are not seen clearly.

| 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?
