A) dimensionally correct
B) dimensionally incorrect
C) numerically incorrect
D) Both [a] and [c]
Correct Answer: D
Solution :
[d] The formula can be written as\[\frac{\text{velocity of light in vacuum}}{\text{velocity of light in medium}}=1\] This formula is dimensionally correct as both the sides are dimensionless. Numerically, this ratio is equal to refractive index which is > 1. Hence, the equation is numerically incorrect.You need to login to perform this action.
