A ray of light travelling in a transparent medium falls on a surface separating the medium from air at an angle of incidence 45

^{\circ}

. The ray undergoes total internal reflection. The possible value of refractive index of the medium with respect to air is

Since- the ray undergoes total internal reflection-xA0-x3BC-gt-1sincNow-i-45Thus- sin-xA0-c-lt-sin-xA0-iThus- -x3BC-gt-1siniOR- -x3BC-gt-x221A-2

A ray of light travelling in a transparent medium falls on a surface separating the medium from air at an angle of incidence $45^{o}$ and undergoes total internal reflection. lf $μ$ is the refractive index of medium the possible values of $μ$ are
$μ = 1.5$
$μ = 1.4$
$μ = 1.6$
$μ = 1.3$
