AIIMS Full Mock Test 3 - Question 27
In the following question, a Statement of Assertion (A) is given followed by a corresponding Reason (R) just below it. Read the Statements carefully and mark the correct answer-
Assertion(A): When light goes from a medium of refraction index 1.5 to a medium of refraction index , 1.6, its speed decreases by 1.875 � 108 m/s.
Reason(R): Refraction index
= s p e e d o f l i g h t i n v a c u u m s p e e d o f l i g h t i n a i r
Detailed Solution for AIIMS Full Mock Test 3 - Question 27
Speed of light in a medium of refractive index 1.5 is 3 � 10 8 1.5 = 2 � 108 m/s
Speed in a medim of refractive index 1.6 is 3 � 10 8 1.6 = 1.875 � 108 m/s
∴ Difference in speed = 2 � 108 - 1.875 � 108 = 1.25 � 107 m/s
