Question

In each of the following questions match column–I and column–II and select the correct match out of the four given choices.

Column : I	Column : II
(i) Snell’s Law	(a) Frequency remains unaffected
(ii) In vacuum	(b) n = [(sin i) / (sin r)]
(iii) In glass	(c) ѵviolet = ѵred
(iv) In going form one medium	(d) ѵviolet < ѵred

(A) i–a, ii–b, iii–c, iv–d 

(B) i–d, ii–c, iii–b, iv–a 

(C) i–b, ii–c, iii–d, iv–a 

(D) i–c, ii–b, iii–d, iv–a

Answer 1

The correct option is (C) i–b, ii–c, iii–d, iv–a.

Explanation:

(i) Snell’s Law → n = [(sin i) / (sin r)] 

(ii) in vacuum → ѵ_violet = ѵ_red 

(iii) in a glass → ѵ_violet < ѵ_red 

(iv) from one medium to other Frequency is always same.
