Which of the color shows maximum refractive index?

(i) What is the value of the angle of deviation of the ray? (iii) Name an instrument where this action of the prism is used.

What will be the unit of refractive index?

Name the behavior shown by light in the given image?

The ratio of speed of light in air to speed of light in any given medium is called as ___________.

What happens to the focal length of convex lens when it is immersed in water??

What can we conclude from the image given?

Complete the ray diagram. What is the angle of deviation in it?

What do you mean by absolute refractive index?

Yellow light is refracted through a prism producing minimum deviation. If i 1 and i 2 denote the angle of incidence and emergence for this prism, then (i) i 1 = i 2 (ii) i 1 > i 2 (iii) i 1 < i 2 (iv) i 1 + i 2 = 90 o

If the refractive index of water is 4/3 and that of glass is 3/2. What will be the refractive index of glass w.r.t. water?

Refraction of light is the phenomenon which takes place due to the difference in the ___________ of the mediums.
