1. Optical fibers: Total internal reflection is used in optical fibers to transmit light signals over long distances with minimal loss of intensity. The light is continuously reflected within the core of the fiber, allowing it to travel long distances without significant attenuation.
2. Reflective prisms: Total internal reflection is used in reflective prisms to redirect light beams at specific angles. This is commonly used in optical instruments such as cameras, binoculars, and telescopes.
3. Endoscopes: Total internal reflection is used in endoscopes to transmit light through a flexible tube and into the body for medical imaging purposes. The light is reflected within the tube to illuminate the internal organs and tissues.
4. Laser cavities: Total internal reflection is used in laser cavities to create a resonant cavity for the laser beam. The light is reflected back and forth between two mirrors, amplifying the intensity of the beam before it is emitted.
5. Optical isolators: Total internal reflection is used in optical isolators to allow light to pass through in one direction while blocking it in the opposite direction. This is useful in preventing feedback and interference in optical systems.
6. Reflective displays: Total internal reflection is used in reflective displays, such as e-readers, to create a high-contrast image without the need for a backlight. The light is reflected within the display to create an image visible to the viewer.

- Fibre optics: Total internal reflection is the principle behind the operation of fibre optics. Light is transmitted through a thin, flexible fibre by multiple total internal reflections. This allows light to be transmitted over long distances with minimal loss. Fibre optics are used in a wide range of applications, including communications, medicine, and sensing. - Prisms: Prisms are used to bend light by refraction. Total internal reflection can occur when light passes from a higher-index medium to a lower-index medium at an angle greater than the critical angle. This can be used to create a variety of optical effects, such as the rainbow and the mirage. - Lenses: Lenses are used to focus light. Total internal reflection can occur when light passes from a higher-index medium to a lower-index medium at an angle greater than the critical angle. This can be used to create a variety of lenses, such as the gradient-index lens and the Fresnel lens. - Mirrors: Mirrors are used to reflect light. Total internal reflection can occur when light passes from a higher-index medium to a lower-index medium at an angle greater than the critical angle. This can be used to create mirrors that are highly reflective and have a wide field of view. - Sensors: Total internal reflection can be used to create a variety of sensors. For example, a total internal reflection sensor can be used to detect the presence of a liquid or gas.
