Properties of Waves Answers

Which are examples of a medium?

A wave of infrared light has a speed of 6 m/s and a wavelength of 12 m. What is the frequency of this wave?

Which refers to the distance between two crests or two troughs on a transverse wave?

2 sets of waves with the top waves labeled A having more closely spaced crests than the bottom waves labeled B.

Marco is conducting an experiment. He knows the wave that he is working with has a wavelength of 32.4 cm. If he measures the frequency as 3 hertz, which statement about the wave is accurate?

What is the speed of a wave with a frequency of 2 Hz and a wavelength of 87 m?

Voices of swimmers at a pool travel 400 m/s through the air and 1,600 m/s underwater. The wavelength changes from 2 m in the air to 8 m underwater. How has the change in media affected the frequency of the wave?

A beam of light is traveling through a medium at 200,000 km/s. It enters a different medium and speeds up to almost 250,000 km/s. Finally, it enters a third medium and halts.What were the media the light traveled through, in order?

Which best describes the relationship between the terms “frequency,” “wavelength,” and “hertz”?

This chart shows characteristics of three different waves, all with the same wavelength of 10 m but moving at different frequencies.
