Question

calculate the absolute refractive index of water (speed of light in water is 2.25X10^8 m/s​

Answer 1

Explanation:

u1 =1 ( another medium is air as its given absolute

v = 3 ×10⁸ m/s

u = 2.25 ×10⁸ m/s

u2 =?

v/u = u2 /u1

3×10⁸ /2.25×10⁸ = u2 /1

u2 = 1.33

Therefore absolute refractive index of water = 1.33

Answer 2

Answer:

u1=1 (another medium is air as its given absolute)

v=3×10^8 m/s

u=2.25×10^8 m/s

u2=?

v/u=u2/u1

3×10^8×2.25×10^8=u2/1

u2=1.33
