Electromagnetic wave theory was given by
Correct answer: C. Maxwell
- A. Newton
- B. Compton
- C. Maxwell
- D. Huygens
Explanation
The correct answer is Maxwell. James Clerk Maxwell developed the electromagnetic wave theory, encapsulated in Maxwell's equations, which describe how electric and magnetic fields propagate through space as waves. These equations laid the foundation for understanding light as an electromagnetic wave.Newton proposed the corpuscular theory of light, which is unrelated to electromagnetic waves. Compton's work focused on scattering phenomena, particularly the Compton effect, rather than wave theory. Huygens contributed to the wave theory of light, but his work predates the comprehensive electromagnetic wave theory established by Maxwell.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
