Question

the rafractive index of water with respect to air is 4/3 . what is the refractive index of air with respect to water ? explain why ?

Answer 1

Answer:

Refractive index of water w.r.t air =n1n2=34 and refractive index of air w.r.t water =n2n1=43=0.

Explanation:

It is speed is 25×108m/s .

Light travels at approximately 300,000 kilometers per second in a vacuum, which has a refractive index of 1.0, but it slows down to 225,000 kilometers per second in water (refractive index of 1.3; see Figure 2) and 200,000 kilometers per second in glass (refractive index of 1.5).
