An example of total internal reflection is when light strikes the boundary between water and air at an angle greater than the critical angle, causing all the light to be reflected back into the water instead of being transmitted. This is why you can see a reflection of the underwater scene when looking at a pond or swimming pool from a certain angle.

How do optical fibers work because of their ability to transmit light signals through total internal reflection?
Optical fibers work by transmitting light signals through total internal reflection. This means that when light enters the fiber at a certain angle, it reflects off the walls of the fiber and continues to travel through it without escaping. This allows the light signals to be transmitted over long distances without losing much of their intensity or quality.
What are the kinds of reflections?
the two ways in which a surface can reflect light are regular reflection and diffuse reflection.
How are heat work and internal energy related?
Heat, work, and internal energy are all forms of energy transfer. Heat is energy transfer due to a temperature difference, work is energy transfer due to a force acting through a distance, and internal energy is the total energy of a system. The change in internal energy of a system is the sum of the heat added to the system and the work done on the system.
What is the principle used in designing periscope?
Periscopes work on the principle of reflection and total internal reflection. Light enters through one end, reflects off a mirror at a 45-degree angle, and then reflects again off another mirror to change the light's direction so it can reach the viewer's eye without being obstructed. This allows the viewer to see objects that are not in their direct line of sight.
What happens to internal energy when mechanical work is done?
When mechanical work is done, the internal energy of a system can change. If work is done on the system, the internal energy increases. Conversely, if work is done by the system, the internal energy decreases. This change in internal energy is governed by the first law of thermodynamics.
What is the principle on which an endoscopy work?
total internal reflection
How does fiber optic communication work?
it works on the principle of total internal reflection
Do you need total internal refraction to get the fiber optics to work?
Not internal refraction - internal reflection. And yes, that's essential to make fiber optics work.

When does reflection work best?
Reflection works best if it is on a smooth shiny surface.
What is a connection between internal and the subject matter of multicultural writing?
Deciding whether or not to stay true to one's heritage is an example of internal conflict.
What are the uses of total internal reflection?
The 'sparkling' of diamonds is due to the way the diamonds are cut, plus the fact that diamonds have a high index of refraction results in the total internal reflection of light. The high index of refraction means that diamonds have a very small minimum critical angle (recall the diamond to vacuum in the observation table). The minimum critical angle in a diamond is 24.4 degrees. Therefore, a lot of the incident light experiences total internal reflection inside the diamond. A ray of light can reflect several times in the diamond before exiting through the top of the diamond. Fibre optics is a technology that uses light to transmit information along a glass table. To achieve the light not escaping as it travels through the cable, it must have a small critical angle so that the light entering it will have an angle of incidence greater than the minimum critical angle for this medium.
What are internal lathe chuck jaws?
Internal chuck jaws are designed to hold the work internally whereas external jaws hold the work externally. If we use a cylinder as an example the internal chuck jaws would fit into the hole and apply outward presure to grip the work. External jaws would sit on the outside of the cylinder and apply preasure inward to hold the work.
Principle of light of a periscope use to work?
The principle behind a periscope is the reflection of light at two or more angles using mirrors to allow an observer to see objects that are not in their direct line of sight. The light enters one end of the periscope, reflects off the mirrors inside, and exits the other end, allowing the observer to see around obstacles or over barriers. This principle is based on the law of reflection, where the angle of incidence is equal to the angle of reflection.
