Electromagnetic radiation with a wavelength of 70.0 mm is in the microwave portion of the electromagnetic...
Microwave ovens heat food by creating microwave electromagnetic radiation that is absorbed by water molecules in the food. Any material that does not have water in it will not absorb the radiation and will not get hot. Metals reflect the microwaves from their surfaces and disrupt the operation of the oven. Some Australians heat water in microwave ovens to make tea. What is the minimum number of microwave photons with a wavelength of 3.17 mm that will have to be...
a microwave oven operates at a frequency of approximately 2450MHz. what is the corresponding wavelength? water, with its polar molecules, absorbs electromagnetic radiation primarily in the infrared portion of the spectrum. Given this fact, why are microwave ovens used for cooking food?
Rank the different types of electromagnetic radiation by wavelength. Longest wavelength Only rank items that are forms of electromagnetic radiation. Shortest wavelength high frequency microwave radiation a high-pitch sound wave radio waves ultraviolet radiation low frequency microwave radiation an orange photon

A typical microwave oven operates using radiation of wavelength 30 mm. What is the frequency of this radiation?
Electromagnetic radiation having a 12.5 mm wavelength is classified as infrared radiation. What is its frequency?
Calculate the energy in joules of microwave radiation of wavelength 12.7 centimeters. (E = hv, h = 6.63 x 10" 1-34 J'sec; speed of light = wavelength x V, speed of light = 3.0 * 108 meters/sec.) Select one: a. 7.3 x 10-19 O b.3.6 x 10-18 c. 4.9 % 1019 O d. 1.6 10-24
Electromagnetic radiation behaves both as particles (called photons) and as waves Wavelength (lambda)j and frequency (nu) are related according to the equation c = lambda Times nu where c is the speed of light (3.00 Times 10^8 m/s). The energy (E in joules) contained in one quantum of electromagnetic radiation is described by the equation E = h Times nu where h it Planck's constant (6.626 Times 10^-34 J s) Note that frequency has units of inverse seconds (s^-1), which...
