gamma rays and radio waves travel with same velocity in free space. distinguish between them in term of origin and the main application
Answers
- Gamma rays are emitted by radioactive nuclei.
- Radio waves are produced by oscillating charges.
- Gamma rays are used for the treatment of cancer.
- Radio waves are used in communication systems.
Answer:
Radio waves are used in communication systems.
Explanation:
Step 1: A emitter produces a radio wave, which a receiver then picks up. A radio transmitter and receiver can both broadcast and receive energy into and from space using an antenna. Typically, transmitters and receivers are made to work over a specific band of frequencies.
Step 2: An example of electromagnetic energy is radio waves. The wavelength of a radio signal is much greater than that of visible light. Radio waves are widely used by people for contact. Both rectangular and circular antennas are used by this radio mast to send and receive radio frequency energy.
Radio frequency (RF) electromagnetic fields with a frequency range of 100 kHz to 300 GHz are frequently produced by modern electronics. Mobile phones, cordless phones, local wireless networks, and radio transmission towers are important producers of RF fields. Radar devices, microwave ovens, and medical scanners all use them as well.
