When a ray of light travels from rarer to denser medium, can the angle of refraction in denser medium be more than the critical angle for the given pair of media?

Expert Answer
Total internal reflection is taking place only if light ray travels from denser medium to rarer medium.
When light ray travels from rarer medium to denser medium , total internal reflection is not taking place.
 
Hence when light ray travels from rarer to denser medium , angle of refraction depends only on Snell's law or law of refraction .
Hence  when light ray travels from rarer to denser medium , angle of refraction can be greater than critcal angle
