Light travels from a rarer medium to a d...

Light travels from a rarer medium to a denser medium. The angle of incidence and refraction are respectively `45^@ and 30^@`. Calculate the refractive index of the second medium with respect to the first medium.

Text Solution

Verified by Experts

Angle of incidence `I = 45^@` : Angle of refraction `r = 30^@`
`""_(1) mu_(2) = (sin i)/(sin r) = (sin 45^@)/(sin 30^@) = (1 sqrt2)/(1 //2) = sqrt2 = 1.414`
