Question

The speed of light in a turpentine oil is 2.04*10raised the power 5 km/s calculate the refractive index of turpentine oil

Answer 1

refractive index (n) = speed of light in air/speed of light in given medium

n= 3×10 raise to power 8/
2.04 × 10 raise power5 ×1000 ( as to convert In meters )
=(after calculation) 25/17
= 1.47
