what is tir and write it's application​

Answer 1

HELLO MATE

Answer:

Total internal reflection is very useful. As a result, it has a number of applications that include: Use in right angled isosceles prism - These prisms can turn light through 90 and 180 degrees based on internal reflection. right angled isosceles prism are mostly used in various optical instruments.

Answer 2

Total Internal Reflection

Total Internal Reflection 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.

Applications of Total Internal Reflection :-

Many Optical Instruments use Right -Angled Prisms to reflect a beam of light through 90° or 180° (By total internal reflection) such as :-

• Cameras
• Binoculars
• Periscope
• Telescope

One of the angles of right angled prism is 90°.
