Question

a) Find the refractive index of kerosene with respect to glass. The
refractive index of kerosene is 1.4 and refractive index of glass
is 1.5.
b) If the refractive index of kerosene is 1.4, what is the speed of
light in kerosene??

Answer 1

$\sf \purple {Answer}$

Let the speed of light in kerosene be 'x' m/sec.

⇒x=2.08×10⁸m/sec.

Therefore, the speed of light in Kerosene

=2.08×10⁸m/sec

Answer 2

$\huge\purple{\mid{\fbox{Solution}}{\mid}}$

Let the speed of light in kerosene be 'x' m/sec.

Kerosene=2.08×10⁸m/sec
