Maxwell’s equations predict that the speed of light in free space is:
A. an increasing function of frequency
B. a decreasing function of frequency
C. independent of frequency
D. a function of the distance from the source
Correct Answer: C
Explanation:
Maxwell’s equations describe the behavior of electric and magnetic fields, including the propagation of electromagnetic waves like light. These equations predict that the speed of light in free space is determined by two fundamental constants: the electric permittivity of free space and the magnetic permeability of free space. These constants do not depend on the frequency of the light.
Therefore, the speed of light in free space is independent of frequency, and statement C is correct.
