Question

a. why is the speed of light through medium C is 0 m/s
b. identify the most probable physical state of A. Give reasons for your answer

c. which of the four media could be air ​

Answer 1

Answer:

Given : Velocity of medium =1.5×10

8

m/sec.

Velocity of light, c=3×10

8

m/sec.

To find : n=?

n=

v

c

n=

1.5×10

8

3×10

8

=2

n=2

Hence, the refractive index of the medium with respect to air is 2.
