Answer:
n = 1.5
Explanation:
The speed of light in vacuum is 300000000 m/s
The speed of light in glass is 200000000 m/s
We need to find the refractive index of the glass.
We know that, the ratio of speed of light in vacuum to the speed of light in medium is equal to refractive index of the medium.
[tex]n=\dfrac{300000000 }{200000000 }\\\\=1.5[/tex]
So, the refractive index of the glass is 1.5.
