Question

Plz help ... this may be the last for today ...​

Answer 1

Answer:

Answer:

Refractive index formula =n=C/V

Here C is speed of light and V is the speed of light in that medium.

Now, we have refractive index of water=4/3 4/3=c/V

V=C/(4/3)

V=Cx3/4

V=3x10⁸x3/4

V=2.26x 10⁸

Lol, Why the question was so long?

if You would had given only to find "the speed of light in water is n=4/3", even then it could have been solved.
