Question

Observe the following table : Material medium P Refractive index 1.52 1.44 10 R S 1.33 In which material medium speed of light is very high?.
A)Q
B)S
C)R
D)P​

Answer 1

Explanation:

Correct option is D) P

Speed of light ,v=μc  

                   where c=speed of light in vacuum

                      and  μ = refractive index of medium

Hence, for maximum speed, μ should be minimum.

Hence, speed of light will be maximum in P having minimum μ.

Answer-(D).

Answer 2

Answer:

answer is option d

Explanation:

because light travels fastest
