According to Maxwell's theory, light consists of:
Correct answer: C. Electric and magnetic field
- A. Magnetic field
- B. Electric field
- C. Electric and magnetic field
- D. None of these
Explanation
According to Maxwell's theory of electromagnetism, light consists of oscillating electric and magnetic fields that propagate through space as electromagnetic waves. Maxwell's equations, formulated in the mid-19th century, describe the behavior of electric and magnetic fields and predict the existence of electromagnetic waves.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
