Question

what is total internal reflection​

Answer 1

Answer:

Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle

Answer 2

• Total internal reflection, complete reflection of a ray of sunshine at intervals a medium like water or glass from the encircling surfaces into the medium.
• The development happens if the angle of incidence is bigger than a precise limiting angle, referred to as the incidence angle.
• Total internal reflection is that the development of bouncing back of sunshine within the same medium once hanging the boundary of a rarer medium.
• This happens once the angle of refraction exceeds 90∘.
• In such a case Snell's law becomes invalid and reflection takes place rather than refraction.
• Mirage is An example of total internal reflection that happens because of region refraction.
