Question

the refractive indices of glass and water with respect to air are 3/2 and 4/3 respectively .if speed of light in glass is 2 x10^8 m/s .find thespeed of light in water​

Answer 1

The refractive indices of glass and water with respect to air are 3/2 and 4/3 respectively .if speed of light in glass is 2 x10^8 m/s .find thespeed of light in water​

Answer

⭕️ Refractive index of medium

✔️ Speed of light in air

________________________

Speed of light in medium

⭕️ 3/2 = speed of light in air

____________________

2 x 10 ^8 m/s

✔️Speed of light in air = 3 x 10 ^8 m/s

⭕️ Speed of light in water

=. 3 x 10 ^8m/s

____________________________

4/3

= 2.25 x 10 ^ 8 m/s ☑️☑️

⭕️ The speed of light in water = 2.25 x 10^8 m/s

Answer 2

2.25 into 10 raise to 8 is the answer
