Light travels through water with a speed of `2.25 xx 10^(8)m//s`. What is the refractive index of water ? Given speed of light in vacuum `= 3xx10^(8)m//s`. |
|
Answer» Here, speed of light in water, `v = 2.25 xx 10^(8)m//s` speed of light in vacuum, `c = 3 xx 10^(8)m//s`, refractive index, `n = ?` From `n = c/v`, `n = (3xx10^(8))/(2.25xx10^(8)) = 1.33` |
