Expert Answer

Speed of light in medium = (2/3) × Speed of light in vacuum

v = (2/3) × c                                       

Refractive index=begin mathsize 14px style fraction numerator Speed space of space light space in space vacuum over denominator Speed space of space light space in space medium end fraction equals straight c over straight v equals fraction numerator straight c over denominator begin display style 2 over 3 end style space straight c end fraction equals fraction numerator 1 over denominator begin display style 2 over 3 end style end fraction equals 3 over 2 end style

Thus, absolute refractive index of medium is equal to 3/2. 

Correct option is (c) -3/2  as per the given question.
