Question

Reftactive index of water w. R t air is 4/3then refractive index of air w.r t water will be

Answer 1

$\Large\underline{\underline{\sf \orange{Given}:}}$

• Refractive index of water wrt to air is $\sf{(\w_mu_a)}$ = 4/3

$\Large\underline{\underline{\sf \orange{To\:Find}:}}$

• Refractive index of air wrt to water is $\sf{(\a_mu_w)}$ = ?

$\Large\underline{\underline{\sf \orange{Solution}:}}$

$\sf{\blue{We\: know \: that ,}}$

$\large{\boxed{\sf \red{\w_mu_a=\dfrac{1}{\a_mu_w}}}}$

${\sf \blue{\therefore \: according \: to \: formula \: Refractive \:index}}$

${\sf \blue{of \: air \: wrt \: water \: will \: be \: {\dfrac{3}{4}}}}$
