Which among the following has a frequency range of 500 kHz to 1000 MHz?
Which among the following has a frequency range of 500 kHz to 1000 MHz? Explanation: 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.
What frequency is 630m?
The 630-meter (or 600-meter) amateur radio band is a frequency band allocated by the International Telecommunication Union (ITU) to amateur radio operators, and it ranges from 472–479 kHz, or equivalently 625.9–635.1 meters wavelength.

What is the 70cm calling frequency UK?
The Seventy Centimetre (70cm) band within the UK is 10MHz wide commencing at 430MHz and extending through to 440MHz. The band is allocated to the Amateur Service with Secondary status and includes additional restrictions in parts of the band.
What electromagnetic waves are used for cooking?
Infrared. Infrared light is used by electrical heaters, cookers for cooking food, and by infrared cameras which detect people in the dark. Infrared light has frequencies which are absorbed by some chemical bonds. The internal energy of the bonds increases when they absorb infrared light, which causes heating.
