A ray of light travelling in a transparent medium falls on a surface separating the medium from air at an angle of incidence `45^(@)`. The ray undergoes total internal reflection. If n is the refractive index of the medium with respect to air, select the possible value (s) of n from the following

Text Solution

Verified by Experts

For total internal reflection to occur,
`I gt ` critical angle c or sin `I gt sin C`
`or sin 45^@ gt 1/mu or 1/sqrt2 gt 1/mu or mu gtsqrt2 or mu gt 1.414`
Possible values of `mu` can be ( c) 1.5 or (d) 1.6
