Question:
What is the scientific phenomenon behind the working of bicycle reflector?
Areflection
Brefraction
Ctotal internal reflection
Ddiffraction
Answer:
C. total internal reflection
Explanation:
When a ray of light enters a medium of higher optical density at an angle of incidence greater than the critical angle, from a medium of higher optical density to a medium of lower light density, the ray is reflected back into the medium without undergoing refraction. This is known as total internal reflection.
