Weekly Exit Ticket Sound Waves

The speed of a sound wave depends on the medium through which it travels. The table shows the speed of sound waves through different media. The greatest increase in the speed of a sound wave would result from the transition between which two media?

• the air into the glass

• the glass into the aluminum

• aluminum into the water

• water into the iron

Which of the following explains sound resonance?

• At a position in space, two sound waves interfere constructively and produce a louder sound.

• An object vibrating at a second object's natural frequency forces the second object to vibrate.

• At a position in space, two sound waves interfere deconstructively and produce an absence of sound.

• An object's motion towards an observer causes sound waves it emits to have a higher perceived frequency.

In a popular television show, the hosts attempt to bust common myths. In one episode, a crystal glass goblet was shattered by a trained singer's voice. What physics phenomenon is responsible for the goblet shattering?

• Doppler effect

• Mach effect

• sound interference

• sound resonance

Doctors use ultrasound imaging to look at organs and other structures within the body. The device sends high frequency waves into the body. How is the image formed when these waves hit boundaries between tissues?

• reflection of sound waves to a probe

• absorption of sound waves by tissues

• disintegration of tissues by the sound waves

• refraction of sound waves to a probe

Sonar equipment sends waves into deep water and measures the

• time delay of the reflected waves.

• refraction of the transmitted waves.

• direction of the transmitted waves.

• interference of the transmitted and reflected waves.

Ultrasonic parking sensors are installed in cars to detect obstacles while parking. These sensors emit a high-frequency sound wave, which hits an object and is then reflected back to the car. How do these sensors work?

• by measuring the temperature of the car and the obstacle

• by measuring the thickness of the car and the obstacle

• by calculating the distance between the car and the obstacle

• by calculating the mass difference between the car and the obstacle
