Physics 2013 JAMB Past Questions - Question 32: Total internal reflection will not occur when light travels fromm

Correct Answer

B

Explanation

one of the conditions for total internal reflection to occur is that light must be incident from an optically dense medium to a less dense one. since glass is optically denser than water. there will be no total internal reflection if light moves from water to glass.Total internal reflection will not occur when light travels from a medium with a higher refractive index to a medium with a lower refractive index.
