Wavelength In Different Media Quick Check
1.) The sound of a plucked guitar string travels through the air and strikes the eardrum of a person in the same room. How does the sound wave change when it transfers from the air to the person’s eardrum?
-Both the speed and the wavelength of the sound change-
2.) The table shows the speed of sound in various media. Which list orders the media from shortest wavelength to longest wavelength for sound waves that pass through them?
-air, water, glass, steel-
3.) Two different types of rope with different properties are fused together to make one long rope. When a wave transfers from the first type of rope to the second type of rope, the wavelength becomes one-fourth of what it was before the transfer. What is true about the speed of the wave?
-The speed of the wave becomes one-fourth its original speed after the transfer-
4.) If a sound wave transitions from one medium to another, which transition would result in a shortening of the wavelength of the sound wave?
-steel to water-
5.) If an ultrasound wave moves from one tissue to another tissue in the body, which of the following transitions will result in the largest change in the wavelength of the ultrasound wave?
-blood to fat-
