प्रश्न
What is linearly polarized light?
उत्तर
Natural light is unpolarised i.e. the electric vector takes all possible directions in the transverse plane, rapidly and randomly, during a measurement. A polarizer transmits only one component (parallel to a special axis). This resulting light is called linear or plane polarized.

| 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 : |
