      • It is caused due to Total internal Reflection.

 

      • It is an optical illusion observed in deserts or hot summer days due to which a person sees a pond of water some distance ahead of him in which the surrounding objects appear inverted.

How Mirage Forms::

 

1. The temperature of other layers of atmosphere goes on decreasing as we go up.
2. Therefore density and refractive index of air changes as one goes up.
3. Thus a ray of light,gets refracted more and more away from the normal.
4. At a particular angle when a ray of light exceeds critical angle, total internal reflection takes place and ray of light gets reflected in the same medium.
5. when the reflected ray reaches our eye, it appears as coming from tree or sky .
6. Hence the inverted image of tree creates an impression from a pond of water.

Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives.


Everyone expected Mary Zophres to win for her retro-revival Technicolor clothes in La La Land — the eventual winner, Colleen Atwood for Fantastic Beasts and Where to Find Them, seemed surprised too. But as other awards began to slip away from the well-reviewed musical, a theme could be teased out. What is Fantastic Beasts if not a plea for equal treatment of people, magical or otherwise? Then, Arrival, a film about the inherent benignity of aliens (read immigrants) won for Best Sound Editing. Hacksaw Ridge, which is, in a way, an anti-guns movie, won in two categories. Fences, about an African-American father who fears racial discrimination, took home the Oscar for Best Supporting Actress. Earlier, Moonlight, featuring two minority communities (black and gay), won for Best Supporting Actor. This turned out to be one of those years the Oscar voter was underestimated. As a majority of voters are actors, there was the tendency to think they'd reward La La Land, a celebration of creation: the heroine wants to make movies, the hero wants to make jazz. It looked like the year of The Artist all over again.

 

Colleen Atwood won which Award?

A) Best Costume Design for La La Land B) Best Supporting Actor for Fantastic Beasts and Where to Find Them
C) Best Supporting Actor for La La Land D) Best Costume Design for Fantastic Beasts and Where to Find Them
 
Answer & Explanation Answer: D) Best Costume Design for Fantastic Beasts and Where to Find Them
