of light reduto benzene from air. If the refractive index of benzene is 1.50, by what percent does the speedof light reduce on entering the benzene?wering plant, summarize the events that take place after fertilization.a3. A ray of light enters into

Answer»

Refractive Index = Speed of light in Air / Speed of light in medium

Speed of light in medium = Speed of light in air / Refractive index

=> Speed of light in medium = 3 × 10⁸ / 1.5

=> Speed of light in medium = 2 × 10⁸ m/s

So, Percentage Change = ( Change in Speed / Speed of light in air ) * 100

=> Change in Speed = 3 × 10⁸ - 2 × 10⁸

=> Change in speed = 10⁸ ( 3 - 2 ) = 10⁸

=> Percentage change = ( 10⁸ / 3 × 10⁸ ) * 100

=> Percentage change = ( 1 / 3 ) * 100

=> Percentage change = 33.34 %
