Answer:
...
The refractive index is 1.33...
Explanation:
...
Speed of light in air =3×10^8 m/s
Speed of.ligt in water = 2.25×10^8m/s
Refractive index of water= speed of light in air/speed of light in medium
=3×10^8/2.25×10^8
=1.33...
see bro when you go through division it come to 1.33 and be sure...the option is 1.4 may be printed by mistake and when you go for practical water refractive index it will 1.33 bro all equation are for ideal conditions which is not possible in real world.So choose the nearest answer that is option a...
