Homework Answers
f = frequency = 2.4 x 109 Hz
q = charge on electron = 1.6 x 10-19 C
m = mass of electron = 9.1 x 10-31 kg
frequency is given as
f = qB/(2m)
2.4 x 109 = (1.6 x 10-19) B/(2 x 3.14 (9.1 x 10-31))
B = 0.086 T

magnetron. The electrons orbit in a 5. (20pts) The microwaves in a microwave oven are produced in a magnetron. The electrons magnetic field at a frequency of 2.4GHz (2.4x10^9 Hz) and as they do so they emit 2.40 electromagnetic radiation (light). What is the strength of the magnetic field? Hint: Assume the electrons move in a circle of radius R (the radius will cancel out in the end). Compare your result Earth's magnetic field.

Which of the following statements correctly describe the various applications listed above?
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...

Problem 7 Two microwave frequencies are authorized for use in microwave ovens: 900 MHz and 2,560 MHz. a) On its highest power setting, a microwave oven can produce 1.00 kW of power onto a 30.0 by 40.0 cm area. What is the intensity in W/m2? b) Calculate the peak electric and magnetic field strength in these waves. c) The maximum safe intensity of microwaves for human exposure is 1.00 W/m. If a radar unit...

As you may well know, placing metal objects inside a microwave oven can generate sparks. Two of your friends are arguing over the cause of the sparking, with one stating that the microwaves "herd" electrons into "pointy" areas of the metal object, from which the electrons jump from one part of the object to another. The other friend says that the sparks are caused by the photoelectric effect. Prove or disprove the latter idea using basic physics. Suppose the typical...
