Question

Light travel through water wi th a speed of 225 ×10,8 m/s what is the refractive index of water​

Answer 1

Answer:

1.33 is is refractive index of water at 20 °C

Answer 2

Answer:

Refractive Index = Velocity in air

Velocity in medium

=

$\frac{3 \times {10}^{8} }{2.25 \times {10}^{8} } \\ = 1.33333$
