How is that in refraction of light energy is lost but not in case of total internal reflection?
Is the loss in total internal reflection exactly zero?
Is the loss in total internal reflection exactly zero?

Total internal reflection zero is the point at which light strikes the interface between two materials at a specific angle, known as the critical angle, and is completely reflected back into the first material without any refraction occurring.
Total internal reflection zero occurs due to the difference in refractive indices between two materials. When light travels from a material with a higher refractive index to one with a lower refractive index, it bends away from the normal line. As the angle of incidence increases, this bending becomes more pronounced until the critical angle is reached and total internal reflection occurs.
Total internal reflection zero is used in many optical devices, such as prisms, fiber optic cables, and optical isolators. It is also utilized in technology such as cameras, binoculars, and microscopes to manipulate light and create images.
Total internal reflection occurs at any angle of incidence greater than the critical angle, while total internal reflection zero specifically refers to the critical angle itself. Total internal reflection zero is a special case of total internal reflection.
No, total internal reflection zero can only occur in materials where the refractive index decreases as the wavelength of light increases. This is known as a dispersive medium and includes materials such as water, glass, and diamond.
