Question

If refractive index of w.r.t is 3/5 and refractive index of w.r.t is 4/7. Find

the refractive index of w.r.t ?​

Answer 1

Answer:-

If relative index of w. r .t is = 3/5

relative index of w.r.t is =4/7

____________________________

Refractive index of w.r.t air =

$\frac{n2}{n1}$

( formula of relative index )

putting the value in formula

4/3

Now,

Relative index of wrt in water =

3/4

=0.75

So it will be 4 / 3 and in water it will be 0.75 .
