Answer 1:: Propagation Speeds Faster Than C Would Induce A Stronger Field and Ever-Increasing

Radio waves travel through space at the speed of light, around 300 million meters per second, much faster than the speed of sound which is about 340 meters per second. Faster propagation speeds than the speed of light c would violate the law of conservation of energy by either inducing ever-increasing field strengths or causing fields to diminish until there was none left. Both incandescent and fluorescent light bulbs emit electromagnetic radiation as light, regardless of their shape.

Answer 1:

Yes, we know Radio wave is an example of electromagnetic wave that travels


through space at the speed of light 3x10^8 m/s whereas the speed of sound is about 340 m/s.
This is the reason that radio wave travels faster than any sound wave without any exception in
every case.

Answer 2:
Propagation speeds faster than c would induce a stronger field and ever-increasing
field strengths and energy. It is against the energy conservation. If propagation fields were less
than c. The fields would get smaller until there was none left, thereby violating the law of the
conservation of energy by destroying it. Therefore, light remains at the consistent critical value,
the speed of light.

Answer 3:
Option C is correct which “Both”. Any object with a temperature emits
electromagnetic waves. This isn't affected by the shape of the bulb. Electromagnetic radiation
is emitted as light. These lights happen to be at the wavelength people can see. As such, they
definitely emit electromagnetic radiation.
