Microwave Oven Quantum Physics
It then considers the absorption of microwaves by foods discussing the dielectric relaxation of water.
Microwave oven quantum physics. Microwaves heat food like the sun heats your face by radiation. Try it and you will understand my saying that the classical beam is composed out of zillions of photons. The work could lead to practical quantum computers that incorporate large numbers of qubits on a single chip. The cooking cavity of a typical microwave oven.

If you know the power of your microwave oven in watts which are per second you can get it to electron volts with this calculator and then divide by the energy of a photon for the frequency of your oven. Chapter 30 quantum physics q 90gp a microwave oven can heat 205 ml of water from 20 0 c to 90 0 c in 2 00 min.
The microwave radiation would be expected to drop off according to the inverse square law so at 20 inches it would be down by about a factor of 100. If the wavelength of the microwaves is λ 12 2 cm how many photons were absorbed by the water. But thereafter i always thought of a microwave oven with no food inside as a potential death ray or at the very least something very hazardous. This is the first of two articles about the physics of microwave ovens.
Microwave ovens are so quick and efficient because they channel heat energy directly to the molecules tiny particles inside food. This strong metal box stops harmful microwaves from escaping. Considering the frequency of 2 450 mhz the wavelength of microwave oven radiation is about 12 cm and the quantum energy of a microwave photon is about 1 x 10 5 ev. Many quantum computer technologies work in the microwave regime while many quantum communications channels such as fiber and satellite work with optical light explained lindsay leblanc who.
Classical physics quantum physics quantum interpretations. This article deals with the generation of microwaves in the oven and includes the operation of the magnetrons waveguides and standing waves in resonant cavities. Assume no loss of heat by the water solution. It then considers the absorption of microwaves by foods discussing the dielectric relaxation of water penetration depths of electromagnetic waves in matter and.
