Question

Match the following terms with their best description Acceptance angle Critical angle Numerical aperture Total internal reflection Core Light-gathering power of an optical fiber. It is proportional to the sine of the acceptance angle. Reflection of light at the interface between media of different refractive indices, when the angle of incidence is larger than a critical angle. Inner part of an optical fiber, has a higher refractive index Minimum incident angle in a medium of higher index for which light is totally internally reflected. Maximum incident angle for which an optical fiber will transmit light by total internal reflection.

Explanation / Answer

According to the the given problem,

1.) Acceptance angle:

Maximum incident angle for which an optical fiber will transmit light by total internal reflection.

2.) Critical angle:

Minimum incident angle in a medium of higher refractive index for which light is totally interally reflected.

3.) Numerical Aperture:

Light gathering power of an optical fiber. It is propoertional to the sine of the acceptance angle.

4.)Total internal reflection,

Reflection of light at the interface between media of different refractive indices, when the angle of incidence is larger than a critical angle.

5.)Core:

Inner part of an optical fiber has a higher refractive index.
