Wave Properties Answers

All parts of the electromagnetic spectrum travel at a speed of 3 × 108 m/s when traveling through no medium. A "vacuum” means that there is no medium, such as a tube without any air in it. Therefore, 3 × 108 m/s is said to be the speed of light in a vacuum.

Which change will decrease the speed of a sound wave traveling through a gaseous matter?

A sound wave has a frequency of 425 Hz. What is the period of this wave?

An FM radio station broadcasts at 9.23 × 107 Hz. Given that the radio waves travel at 3.00 × 108 m/s, what is the wavelength of these waves?

The diagram shows a wave traveling through a medium.

The speed of sound in ice, water, and steam is shown.

A frequency generator sends a 550 Hz sound wave through both water and ice.

Study the diagram.

The diagram represents wavelengths of different colors of visible light that pass by in a specific time period.

What best describes the relationship between wavelength and frequency in an electromagnetic wave?
