Question

The absolute refractive index of a water is 1.33 the speed of a light in Water will be

Answer 1

Answer:

2.25×10^8 m/s

Explanation:

we know that,

refractive index=speed of light in vaccum

____________________.

speed of light in water.

to find speed of light in water. speed of light in water= speed of light in vaccum.

___________________

refractive index

V=C/N

V=3×10^8/(1.33)

then,

V=2.25×10^8 m/s. or/.

225 ,000 killometers per second
