Accelerating electric charge emits electromagnetic radiation. How does this apply in each case: (a) radio waves, (b) infrared radiation.
In which pan of the electromagnetic spectrum are each of these waves: (a) f=10.0kHz , (b) f==750nm , (C) f=1.25108Hz , (d) 0.30 nm
Make a list of some of the many practical consequences of Maxwell’s theory of electromagnetic waves (television is one example).
A microwave oven uses electromagnetic waves of frequency f=2.45109 to heat foods. The waves reflect from the inside walls of the oven to produce an interference pattern of standing waves whose antinodes are hot spots that can leave observable pit marks in some foods. The pit marks are measured to be 6.0 cm apart. Use the method employed by Heinrich Hertz to calculate the speed of electromagnetic waves this implies.
Illustrate that the size of details of an object that can be detected with electromagnetic waves is related to their wavelength, by comparing details observable with two different types (for example, radar and visible light or infrared and X-rays).
Review. A microwave oven is powered by a magnetron, an electronic device that generates electromagnetic waves of frequence 2.45 GHz. The microwaves enter the oven and arc reflected by the walls. The standing-wave pattern produced in the oven can cook food unevenly, with hot spots in the food at antinodes and cool spots at nodes, so a turntable is often used to rotate the food and distribute the energy. If a microwave oven intended for use with a turntable is instead used with a cooking dish in a fixed position, the antinodes can appear as burn marks on foods such as carrot strips or cheese. The separation distance between the burns is measured to be 6 cm 5%. From these data, calculate the speed of the microwaves.
Determine the amount of time it takes for X-rays of frequency 31018Hz to travel (a) 1 mm and (b) 1 cm.
How does the wavelength of radio waves for an AM radio station broadcasting at 1030 KHz compare with the wavelength of the lowest audible sound waves (of 20 Hz). The speed of sound in air at 20 °C is about 343 m/s.
