What are the frequencies of the electromagnetic spectrum?
| Region | Wavelength | Frequency |
|---|---|---|
| Visible (blue) | 400 nm | 7.5 × 1014 Hz |
| Visible (red) | 700 nm | 4.3 × 1014 Hz |
| Infrared | 10000 nm | 3 × 1013 Hz |
| Microwave | 1 cm | 30 GHz |
What are the 7 members of the electromagnetic spectrum?
The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.
Who is the owner of spectrum in India?
Reliance Jio Infocomm Ltd said it acquired the right to use spectrum in all the 22 circles or zones across India. In all, it won 488.35 MHz of spectrum, taking up its spectrum footprint by 55 per cent to 1,717 MHz (uplink + downlink).
How far can electromagnetic waves travel?
As to how far they can travel in a vacuum, the electromagnetic force reaches to infinity. Radio waves are part of the electromagnetic spectrum, so the answer is any distance you care to mention. I think the furthest yet detected by radio telescopes have travelled nearly 14 billion miles.
What are microwave frequencies?
Microwave is a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively. In all cases, microwaves include the entire SHF band (3 to 30 GHz, or 10 to 1 cm) at minimum.
What frequency are xrays?
X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10−8 to 10−12 metre and corresponding frequencies from about 1016 to 1020 hertz (Hz).

Who will launch 5G network first in India?
Bharti Airtel
Airtel said it conducted India’s first rural 5G trial with Swedish telecom equipment maker Ericsson on the outskirts of Delhi. Bharti Airtel has said that the first 5G network will be launched within two-quarters of spectrum auction and can cover a large part of the country after one year.
What color has the highest frequency?
Violet
Violet waves have the highest frequencies. Red waves have the longest wavelengths.
Which is the highest frequency in the electromagnetic spectrum?
Very high frequencies (VHFs) encompass the 30- to 300-MHz range. This popular frequency range is use by many services, including mobile radio, marine and aeronautical communication, FM radio broadcasting (88 to 108 MHz), and television channels 2 through 13.
How are radio bands allocated in the radio spectrum?
Radio bands by frequency. A radio band is a small contiguous section of the radio spectrum frequencies, in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.
What’s the maximum amount of spectrum that can be allocated to one company?
The maximum frequency spectrum that could be assigned to one company on the 1800 MHz band was 2 x 20 MHz, thus existing mobile operators could gain only 2 x 4.8 MHz each. According to ECC decision 2600 MHz band was split into two categories: FDD with 14 blocks of 2 x 5 MHz and TDD with 10 blocks of 1 x 5 MHz each.
What are the radio frequencies in the United States?
Broadcast frequencies: Longwave AM Radio = 148.5 kHz – 283.5 kHz (LF) Mediumwave AM Radio = 525 kHz – 1710 kHz (MF) Shortwave AM Radio = 3 MHz – 30 MHz (HF)
