Open in App
Solution

Electromagnetic radiation:

  1. Radiation that passes in waves and has both electric and magnetic fields is called electromagnetic radiation.
  2. The speed or velocity of electromagnetic waves in a vacuum is determined by the radiation source.
  3. Whenever we progress from gamma rays to radio waves, the frequency lowers and the wavelength grows, allowing the composition to remain constant.
  4. Through a vacuum, All electromagnetic radiation travels at the same speed, which is about 3.0×108meterspersecond.

Therefore, electromagnetic radiation travels through a vacuum at a speed of 3.00×108m/s.
