Question

Refractive indexes of kerosene, turpentine, and
water are 1 44, 1 47 and 1 33 respectively Through which of these
media speed of light is (i) maximum and (ii) minimum
Explain

Sanat K Mukherjee · Accepted Answer

Dear Student,
Refractive index of a medium is defined as the ratio of speed of
light in vacuum to that in the medium Thus, greater the refractive
index of a medium, smaller is the speed in the medium
(i) Water has the minimum refractive index among the three so speed
of light is maximum in water
(ii) Turpentine has the maximum refractive index among the three so
speed of light is minimum in turpentine
