I have been asked this question in class test.

The above asked question is from Electromagnetic Spectrum in chapter Electromagnetic Waves of Physics – Class 12

Answer 1

The correct choice is (c) Radio Waves

For explanation I would say: Radio Waves are generally in the frequency range ➔ 500 kHz to 1000 MHz. Radio waves are used for long-distance communication, such as in television, mobiles, and radios. These devices receive radio waves and convert them to mechanical vibrations in the speaker to create sound waves.
