Question

If the absoluta refractive index
of glass and water is 3/2 and 4/3 respectively then find of
speed of light in water and
glass​

Answer 1

Explanation:

Given

nwater =4/3

nglass =3/2

vglass =210^8m/s

nair =1

Speed of light in a medium c/n

Where c and n are the speed of light in vacuum and retractive index of medium respectively

(a) vglass= c/nglass

=210^8 =c/(3/4)=310^8m/s

(b) vwater= c/nwater

v310^8=/(4/3)=22.610^8
