PHY 104 Reflection and Refraction of Light Objective Question

Question

Which of the following technological applications relies on total internal reflection?
Options
A Telescopes using large concave mirrors.
B Microscopes using multiple lenses.
C Fiber optics for transmitting light signals.
Correct Answer
D Diffraction gratings for separating light into colors.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 51 explicitly states: 'Optical fibers also depend on total internal reflection; they are therefore able to transmit light signals with very small losses.' Page 50 also mentions binoculars using total internal reflection for true 100% reflection.

Hint

Consider applications where light needs to be guided or reflected with high efficiency within a medium.
