Q. Which is the most important prediction to emerge from Maxwell's equations?

Electromagnetic Waves

Solution:

The most important prediction to emerge from Maxwell's equations is the existence of electromagnetic waves, which are (coupled) time-varying electric and magnetic fields that propagate in space. The speed of the waves, according to these equations, turned out to be very close to the speed of light $\left(3 \times 10^{8} ms ^{-1}\right)$, obtained from optical measurements. This led to the remarkable conclusion that light is an electromagnetic waves.
