Gamma rays and radio waves travel with the same velocity in free space. Distinguish between them in tems of their origin and the main application.

Text Solution

Verified by Experts

Gamma rays and radio waves both travel with the same velocity in free space because both of them are electromagnetic waves. Differences between them are:
(i) Origin: Gamma rays are produced in nuclear reactions and during radioactive decay but radio waves are produced by the accelerated motion of charges in conducting wires
(ii) Application: Gamma rays are used in medicine to destroy cancer cells but radio waves are used in radio and TV communication systems.
