Physics Question on Ray optics and optical instruments
Optical fibre are based on
A
Total internal relfection
B
Less scattering
C
Refraction
D
Less absorbtion coefficient
Answer
Total internal relfection
Explanation
Solution
The correct option is(A): Total internal relfection. In the realm of fiber optic transmission, information is conveyed from one end to another by utilizing light waves traveling through a glass medium. The accompanying diagram illustrates a standard optical fiber. Within this fiber, the central core possesses a higher refractive index compared to the surrounding cladding. Light travels through this core and experiences total internal reflection upon encountering the core's boundary. Utilizing optical fibers for data transmission has demonstrated itself as the most efficient means of communication.
