A microwave is an electromagnetic wave, a type of non-ionizing radiation that is commonly used in cooking appliances to heat food.
Yes, because it has a charge (+). Any charged particle that vibrates produces an electromagnetic wave at the frequency determined by the number of vibrations per second. The magnitude is determined by the how far the particle goes from max. to min. on each cycle.
The Greek letter "gamma" (γ) represents a type of high frequency electromagnetic radiation known as gamma rays. Gamma rays have the shortest wavelengths and highest frequencies in the electromagnetic spectrum.
An electromagnetic wave with a longer wavelength will have a smaller frequency, and less energy per photon.An electromagnetic wave with a longer wavelength will have a smaller frequency, and less energy per photon.An electromagnetic wave with a longer wavelength will have a smaller frequency, and less energy per photon.An electromagnetic wave with a longer wavelength will have a smaller frequency, and less energy per photon.
Electromagnetic waves are a type of energy that can travel through a vacuum or a medium. They have both electric and magnetic components that oscillate perpendicular to each other and to the direction of wave propagation. These waves have a wide range of frequencies and wavelengths, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. They can travel at the speed of light and do not require a medium to propagate.
