Total internal reflection takes place when the light ray travels from ______
Total internal reflection takes place when the light ray travels from ______
Open in App
Solution
The correct option is C Denser to rarer medium
Total internal reflection always place when a light ray travels from an optically denser medium to a rarer medium. For total internal reflection, angle of incidence must be greater than the critical angle,
C=sin−11μ where, μ=refractive index of denser medium relative to rarer medium.
