Q1380
Fiber optics cable used in communication, works on the principle of
A.
Regular reflection of light
B.
Diffuse reflection of light
C.
Refraction of light
D.
Total internal reflection of light
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
Optical communication utilizes the principle of total reflection. When the injection angle of light satisfies certain conditions, light can form total reflection in the optical fiber, thereby achieving the purpose of long-distance transmission.
