A microwave oven works by passing microwave radiation, usually at a frequency of 2450 MHz (a wavelength of 12.24 cm ), through the food.
Read moreWhat is the wavelength of a radiofrequency radiation that has a frequency of 2450 MHz?
a) 2450 MHz radiation has a frequency of 2450 million hertz (2450 x 106) or 2.450 x 109 Hz. This frequency corresponds with a wavelength of about 10-1 meters or 10 cm.
Read moreWhat is the wavelength of radiation in your microwave oven whose frequency is 2.45 GHz?
Following international conventions, microwave ovens at home or in restaurants operate at frequencies of about 2.45 GHz, i.e. λ = 12. 23 cm .
Read moreWhat is the wavelength of microwave oven waves?
The microwave region extends from 1,000 to 300,000 MHz (or 30 cm to 1 mm wavelength) . Although microwaves were first produced and studied in 1886 by Hertz, their practical application had to await the invention of suitable generators, such as the klystron and magnetron.
Read moreWhy do microwave ovens operate at 2.45 GHz?
They’d been around commercially since 1947. And generally, they operated at a specific frequency: 2.45 GHz. Despite heavy shielding, microwave ovens’ powerful emissions could sometimes interfere with neighboring frequencies, so it was decided that they should be given a few megahertz of space in both directions .
