प्रश्न
Answer the following question.
Gamma rays and radio waves travel with the same velocity in free space. Distinguish between them in terms of their origin and the main application.
उत्तर
Gamma rays are produced from radioactive decay of the nucleus while radio waves are produced from rapid acceleration and decelerations of electrons in aerials.
Gamma rays are used as catalyst in the manufacturing of some chemicals. They are also used in treatment of cancer.
Radio waves are used in radio and television communication and broadcasting.
