Electromagnetic radiation behaves both as particles (called photons) and as waves. wavelength (λ) and frequency (ν) are related according to the equation c=λ×ν where c is the speed of light (3.00×108 m/s). the energy (e in joules) contained in one quantum of electromagnetic radiation is described by the equation e=h×ν where h is planck's constant (6.626×10−34 j⋅s). note that frequency has units of inverse seconds (s−1), which are more commonly expressed as hertz (hz). a microwave oven operates at 2.20 ghz . what is the wavelength of the radiation produced by this appliance?

Electromagnetic radiation is more common than you think. radio and tv stations emit radio waves when they broadcast their programs; microwaves cook your food in a microwave oven; dentists use x rays to check your teeth. even though they have different names and different applications, these types of radiation are really all the same thing: electromagnetic (em) waves, that is, energy that travels in the form of oscillating electric and magnetic fields.the frequency and wavelength of em waves can vary over a wide range of values. scientists refer to the full range of frequencies that em radiation can have as the electromagnetic spectrum.electromagnetic waves are used extensively in modern technology. many devices are built to emit and/or receive em waves at a very specific frequency, or within a narrow band of frequencies. here are some examples followed by their frequencies of operation: * garage door openers: 40.0 \rm mhz,* standard cordless phones: 40.0 to 50.0 \rm mhz,* baby monitors: 49.0 \rm mhz,* fm radio stations: 88.0 to 108 \rm mhz,* cell phones: 800 to 900 \rm mhz,* global positioning system: 1227 to 1575 \rm mhz,* microwave ovens: 2450 \rm mhz,* wireless internet technology: 2.4 to 2.6 \rm ghzpart bwhich of the following statements correctly describe the various applications listed above? check all that apply.all these technologies use radio waves, including low-frequency microwaves.all these technologies use radio waves, including high-frequency microwaves.all these technologies use a combination of infrared waves and high-frequency microwaves.microwave ovens emit in the same frequency band as some wireless internet devices.the radiation emitted by wireless internet devices has the shortest wavelength of all the technologies listed above.all these technologies emit waves with a wavelength in the range 0.10 to 10.0 \rm m.all the technologies emit waves with a wavelength in the range 0.01 to 10.0 \rm km.
