Light travels with a velocity ${\sf 1.5×10^8\:m/s}$ in a medium. On entering second medium it's velocity becomes ${\sf 0.75×10^8\:m/s}$ what is the refractive index of the second medium with respect to the first medium.

$\huge\underline{\underline{\bf \green{Solution-}}}$

✪$\large{\boxed{\bf \blue{_2 \mu_1=\dfrac{v_1}{v_2}} }}$

$\implies{\sf _2\mu_1=\dfrac{1.5×10^8}{0.75×10^8} }$

$\implies{\bf \red{ _2\mu_1=2}}$

$\huge\underline{\underline{\bf \green{Answer-}}}$

Refractive index of second medium with respect to first medium is ${\bf \red{2}}$

Answer 2

Answer:

The refractive index is 2....
