Question

velocity of light in a medium 3×10^8 what is refractive medium of this index​

Answer 1

Answer:

The refractive index of medium is 1

Explanation:

n = c /v

where :

• n is refractive index
• c is the speed of light in vacuum  ( c = 3 x $10^{-8}$ m/s )
• v is velocity of light in the medium

n = 3 x $10^{-8}$ / 3 x $10^{-8}$

  = 1

The medium having n = 1 is air.
