Accelerating electromagnetic charges radiate electromagnetic waves which propagate at the
Correct answer: C. speed of light
- A. speed of electromagnetic waves
- B. Frequency of light
- C. speed of light
- D. Frequency of electromagnetic waves
Explanation
Accelerating electromagnetic charges, such as electrons, radiate electromagnetic waves, which are a combination of electric and magnetic fields. These waves propagate through the electromagnetic field at a constant speed, which is:c = 299,792,458 meters per second (m/s)This speed is known as the speed of light, and it is a fundamental constant of the universe

About Electromagnetic Waves
Electromagnetic waves consist of mutually perpendicular, oscillating electric and magnetic fields that also remain perpendicular to the direction of propagation. They travel through vacuum at the speed of light and include radio waves, microwaves, infrared, visible, ultraviolet, X-rays and gamma rays. Unlike mechanical waves, they do not require a material medium.
