Question

the speed of the light in an unknown medium is measured to be 2.76×10^8 m/s. what is refractive index of the medium?​

Answer 1

Answer:

(3*10^8)/(2.76*10^8) = 1.087

Explanation:

Refractive index (n)= c/v

c =  velocity of light in air

v = velocity of light in medium

Hey broh !

u look so cute !

have a good day !
