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 MHz,
standard cordless phones: 40.0 to 50.0 MHz,
baby monitors: 49.0 MHz,
FM radio stations: 88.0 to 108 MHz,
cell phones: 800 to 900 MHz,
Global Positioning System: 1227 to 1575 MHz,
microwave ovens: 2450 MHz,
wireless Internet technology: 2.4 to 2.6 GHz.

Brian is speaking to you and a group of friends. he explains that nuclear power plants are essentially nuclear bombs waiting to explode. this is very worrisome to your friends. which statement is best suited to discredit brian and put your friends at ease? select all that apply. -nuclear power plants and nuclear bombs both use nuclear fission to generate energy, but a nuclear power plant very precisely controls the intensity of the reaction while a nuclear bomb releases the energy in one big explosion. -nuclear power plants use nuclear fusion to generate energy, but a nuclear bomb relies on nuclear fission. since, their reactants differ, their reactions differ. -nuclear power plants have never exploded in their 60 year history. -you agree with brian's statement.
