What is the wavelength of microwave oven waves?

A microwave oven works by passing microwave radiation, usually at a frequency of 2450 MHz (a wavelength of 12.24 cm ), through the food.

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.

Following international conventions, microwave ovens at home or in restaurants operate at frequencies of about 2.45 GHz, i.e. λ = 12. 23 cm .

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.
