When and where do we see a rainbow How is a rainbow formed Class 10?
Ans. Rainbow can be seen throughout rains It is constantly formed in an instructions opposite to that of the Sun. When light ray falls on the bead it distributes into its constituent colours and due to overall internal reflection of this dispersed light then it once again refracts and we see rainbow opposite to the Sun.
How will you describe the development of rainbow from your activity?
Every bead within the arc is refracting and distributing the whole noticeable light spectrum (ROYGBIV). … Rainbows are not restricted to the dispersion of light by raindrops. The splashing of water at the base of a waterfall triggered a mist of water in the air that frequently leads to the development of rainbows.

Why do stars sparkle Class 10?
The twinkling of stars is due to climatic refraction of star-light The refraction of light brought on by the earth’s environment having air layers of differing optical density is called climatic refraction. … This triggers the light from the star to sparkle when seen from the ground.

What is angle of prism?
The angle formed due to 2 lateral faces of the prism is referred to as the angle of prism. The 2 lateral faces are from where the light participates in the prism and the light heads out after refraction.
