Light enters from air to glass having refractive index \(1.50\). What is the speed of light in the glass? The speed of light in vacuum is \(3 \times 10^8\ ms^{-1}\)
  
Let us consider,
\(c\) - Speed of light in vacuum
\(n_g\) - Refractive index of glass
\(v\) - Speed of light in the glass
 
Then, the formula to calculate \(v\) is,
Speed of light in the glass (\(v\)) \(=\)  \(\times 10^8\ ms^{-1}\)
