The given statement is true.
Concept: Here we have to write the condition for total internal reflection and relation between refractive index and critical angle, thus by phenomena of total reflection.
When light travels from a rarer medium to denser medium and reflects to the original medium, it is known as reflection.

The condition for total internal reflection is:
The light must travel from one medium to another medium i.e. denser to rare.The angle of incident must be greater than critical angle.
Hence, the given statement is true.
