Electromagnetic waves transport:
Correct answer: A. Energy
- A. Energy
- B. Mass
- C. Heat
- D. None
Explanation
Electromagnetic waves, including light, are a form of energy transfer. They do not carry mass; instead, they transport energy through space. This energy can manifest as light, heat, or other forms, depending on the nature and frequency of the electromagnetic waves.- (a) Energy: Correct. Electromagnetic waves transport energy as they propagate through space.- (b) Mass: This is not correct. Electromagnetic waves do not transport mass.- (c) Heat: Electromagnetic waves can contribute to the transfer of heat, but they are not solely responsible for heat transport. Heat can be transferred through various mechanisms.- (d) None: This is not correct. Electromagnetic waves do transport energy.So, the correct answer is (a) Energy. Electromagnetic waves primarily transport energy through space.

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.
