Question

Is the refractive index of water w.r.t. glass less or more than 1?

Answer 1

it is less than oneeeeeeer

Answer 2

Answer:

this is your ans

Explanation:

Refractive index of medium 2 w.r.t. medium 1 is written as n21 = speed of light in medium 1/ speed of light in medium 2 n21 = v1/v2 Refractive index of glass w.r.t. air nga = 1.65 = va/vg ⇒ vg = va/1.65 Refractive index of water w.r.t. air nwa = 1.33 = va/vw ⇒ vw = va/1.33 Refractive index of water w.r.t. glass nwg = vg/vw = ( va/1.65)/(va/1.33) = 1.33/1.65 = 0.80
