# (I) What is the Relation Between the Refractive Index of Water with Respect to Air ( a μ W ) and the Refractive Index of Air with Respect to Water ( W μ a ) . - Physics

Short Note

(i) What is the relation between the refractive index of water with respect to air ("_aμ_\text(w)) and the refractive index of air with respect to water ("_\text(w)μ_ a) .
(ii) If the refractive index of water with respect to air ("_aμ_\text(w)) is5/3. Calculate the refractive index of air with respect to water ("_\text(w)μ_ a) .

#### Solution

(i)  "_a μ_\text(w) =(mu_\text(w))/(mu_a)

 "_\text(w) μ_a   = (mu_a)/(mu_\text(w)

∴ "_a μ_\text(w) = 1/ ("_\text(w) mu_a)

(ii)   "_a μ_\text(w) = 5/ 3

 "_\text(w) mu _a = 3/5
