If the absolute refractive indices of water and glass are and respectively, what is the refractive index of glass with respect to water ()?
Answer and explanation
Correct answer: C.
- Step 1: Recall the relative refractive index formula: the refractive index of medium 2 with respect to medium 1 is .
- Step 2: Substitute given values: .
Answer
.
Why not the others: '' calculates water with respect to glass (); '' and '' use incorrect algebraic ratios.
