Question

refractive index of benzene 3\2 find the speed of light in benzene​

Answer 1

Answer:

You should remember the relationship between speed of light in a medium and the refractive index of the medium.

conventionally, speed of light in vacuum is taken as 3* 10^8 m/s.

So the formula to be remembered is:

speed of light in a medium( benzene)

speed of light in a medium( benzene) =speed of light in vacuum/ refractive index of that medium

As per the formula,

speed in benzene =( 3*10^8)/ (3/2)

=( 2 *10^8) m/s

The answer is 2* 10^8 m/s.

Answer 2

Answer:

I know only second one 2×10 power8 m/ s
