The conditions for total internal reflection are the the light is travelling from an optically denser medium (higher refractive index) to an optically less dense medium (lower refractive index) and that the angle of incidence is greater than the critical angle.

Total internal reflection is a phenomenon that occurs at the boundary between two mediums, such that if the incident angle in the first medium is greater than the critical angle, then all the light is reflected back into that medium.

A good example of total internal reflection is a diamond. Diamond has the highest index of refraction, but can increase the amount of total internal reflection by being cut properly making diamond sparkle. ... Total internal reflection occurs when the angle of incidence is equal to or greater than the critical angle.

Explanation:
Total internal reflection occurs when a light ray traveling from a denser medium encounters a boundary with a less dense medium and the angle of incidence is greater than the critical angle. The critical angle is the angle of incidence at which the angle of refraction is 90 degrees.

Reasons for Total Internal Reflection:
Total internal reflection occurs due to the following reasons:
- When light travels from a denser medium to a less dense medium, it bends away from the normal to the surface of separation. This phenomenon is called refraction.
- When the angle of incidence is increased beyond a certain value, the angle of refraction becomes 90 degrees. This angle is known as the critical angle.
- At angles of incidence greater than the critical angle, the light is reflected back into the denser medium. This phenomenon is called total internal reflection.

Example:
An example of total internal reflection is the mirage. When light travels from a hotter region of air (less dense) to a cooler region of air (denser), it bends away from the normal to the surface of separation. This causes the image of an object to appear higher than its actual position. This is because the light rays from the object undergo total internal reflection at the boundary between the hot and cool air layers.

Conclusion:
In conclusion, total internal reflection occurs when light travels from a denser medium to a less dense medium and the angle of incidence is greater than the critical angle. Total internal reflection has many practical applications, including in fiber optics, binoculars, and periscopes.
