Radio waves microwaves

So the frequency (energy) used in a microwave oven is changed slightly to one that will penetrate about 1cm into the food Conduction and convection processes then spread the heat through the food As our bodies contain water molecules in our cells microwave oven radiation will heat up our cells and is very dangerous at high intensity because

Radiofrequency (RF) Radiation

They come from radio and television broadcasts WiFi and Bluetooth devices cell phones (and cell phone towers) and other sources Some common uses of RF radiation Microwave ovens Microwave ovens work by using very high levels of a certain frequency of RF radiation (in the microwave spectrum) to heat foods

Basics of Radio Waves

f = c / λ and λ = c / f The higher the frequency the shorter the wavelength and vice versa Radio waves oscillate at frequencies between the upper end of human hearing at about 20 kilohertz or kHz (kilo is the metric abbreviation meaning 1 000) on up to 1 000 gigahertz or GHz (giga is the metric abbreviation meaning 1 billion) They have corresponding wavelengths from

Effect of radio frequency heat treatment on protein

Jan 15 2019Radio frequency is non-ionizing electromagnetic waves with the frequency range between 1 and 300 MHz and wavelength of up to 11 m Radio frequency wave can penetrate deep into the dielectric materials such as food and produce heat volumetrically through dipole rotation and/or ionic polarization ( Hou et al 2016 Marra et al 2009 )
