What is total internal reflection ?

Where the phenomena of total internal reflection can be observed ?

Explain the phenomena of total internal reflection in right angle prism.

As shown in figure, a ray of light is incident on glass cube. If it experiences total internal reflection in vertical plane, then what is the refractive index of glass?

A cubical block of glass of refractive index n_1 is in contact with the surface of water of refractive index n_2. A beam of light is incident on vertical face of the block. After refraction a total internal reflection at the base and refraction at the opposite face take place. The ray emerges at angle theta as shown. The value of theta is given by

Which of the following phenomenon doesn.t depend on total internal reflection ?

A ray of light enters in denser medium from rarer medium. Speed of light in rarer medium is double than that in denser medium, what is the critical angle for total internal reflection ?

Assertion : The images formed by total internal reflections are much brighter than those formed by mirrorrs or lenses. Reason : There is no loss of intensity in total internal reflection.
