Question

if the absolute refractive index of glass and water is 3/2 and 4/3 recpestively then find the ratio of of speed of light in water and glass​

Answer 1

Answer:

Plz mark it branliest

Explanation:

Given :    nwater=34           nglass=23             vglass=2×108  m/s            nair=1

Speed of light in a medium        vmedium=nc         

where  c and n are the speed of light in vacuum and refractive index of medium respectively.

(a) :     vglass=nglassc

∴     2×108=(3/2)c                        ⟹c=3×108  m/s

(b) :     vwater=nwaterc

∴     vwater=(4/3)3×108=2.26×108  m/s
