Question
The refractive index of water is:
(a) 1.33
(b) 1.50
(c) 2.42
(d) 1.36
Solution
1.33
Explanation:
Velocity of light in water = 225,563,010 m/s
Velocity of light in air = 300,000,000 m/s
Refractive index= `"velocity of light in air "/("velocity of light in water")`
`(300,000,000)/(225,563,010)`
=1.33
