iv)Through which of these media,will the speed of light be maximum?
(1)
b) B
a) A
d) D
c) C
v)What will be the refractive index of B relative to C. ?
a)more than 1
b)less than 1
(1)
c)equal to 1
d) equal to zero​

Answer 1

Answer:

1. Higher the angle of refractions, lesser the optical density and vice versa

Since medium c has th loves tangle of refraction it has the maximum optical density.

2. lower the optical density , higher the speed of light . Refer to ‘1.’ .

So medium a will have maximum speed of light

3.light will bend toward the normal

4 we can calculate the refractive index and write this

Refractive index of b is less than the refractive index of

Hope this help

I sorry if there is a mistake

If there is please comment and I will correct it
