Question

d) i) If the refractive index of glass is 1.5, what is the speed of light in glass?
ii) Name the phenomena responsible for the formation of rainbow in the sky after rains.​

Answer 1

Explanation:

1.Speed of light in glass is given by the relation,

1.Speed of light in glass is given by the relation, Hence, the speed of light in glass is 2 × 108 m/s.

1.Speed of light in glass is given by the relation, Hence, the speed of light in glass is 2 × 108 m/s.2.A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.
