1.	The refractive index of water will be(a) 1(b) 2.66(c) 5(d) 1.33This question was addressed to me by my school teacher while I was bunking the class.My question is from Refractive Index and Numerical Aperture topic in portion EM Wave Propagation of Electromagnetic Theory
Answer» RIGHT CHOICE is (d) 1.33 For EXPLANATION I WOULD say: The velocity of light in water as medium will be 2.25 x 10^8. On substituting for the speed of light, we get refractive index as n = 3/2.25 = 1.33(no unit).
