In vacuum all electromagnetic waves have the same:
Correct answer: A. Speed
- A. Speed
- B. Energy
- C. Frequency
- D. Wavelength
Explanation
All electromagnetic radiations such as microwave, gamma rays or radio waves travel with a speed of light in a vacuum which is equal to 3.0 x 108 meters per second. This is because all massless particles travel with the speed of light. Since light is massless, therefore all particles travel with speed of light. So, the correct answer is option A.
