Question

what is Total internal reflection ? Also give it's necessary conditions.
​

Answer 1

Answer:

) Necessary conditions for total internal reflection to occur are: (i) The incident ray on the interface should travel in optically denser medium. (iii) The angle of incidence should be greater than the critical angle for the given pair of optical media

Explanation:

· The conditions necessary for the phenomena to take place are: Light should travel from denser medium to the rarer medium. Angle of incidence should be greater than the critical angle in denser medium for a pair of media in contact.
