Which waves have some electrical properties and some magnetic properties?

You will learn that light is an electromagnetic wave that can travel through a vacuum. Can sound waves travel through a vacuum?

What are the differences between light waves and sound waves?

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

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.

Give an example of resonance in the reception of electromagnetic waves.

An electromagnetic wave has a frequency of 12 MHz. What is its wavelength in vacuum?

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.

Radio waves transmitted through space at 3.00108m/s by the Voyager spacecraft have a wavelength of 0.120 m. What is their frequency?

How does the intensity of an electromagnetic wave depend on its electric field? How does it depend on its magnetic field?
