Sound Waves

How does sound travel through different mediums?

• Sound travels faster in gases than in liquids, and faster in liquids than in solids.

• Sound travels at the same speed in all mediums.

• Sound travels faster in solids than in liquids, and faster in liquids than in gases.

• Sound travels faster in liquids than in gases, and slower in solids than in liquids.

What determines how loud or soft a sound is?

• Frequency

• Wavelength

• Amplitude

• Pitch

What is the speed of sound in air at room temperature?

• Approximately 300 meters per second.

• Approximately 343 meters per second.

• Approximately 400 meters per second.

• Approximately 250 meters per second.

What does low amplitude indicate about a sound?

• Louder Sounds

• Quieter Sounds

• Higher Pitch Sounds

• Lower Frequency Sounds

What is the unit of measurement for frequency?

• Decibel (dB)

• Hertz (Hz)

• Newton (N)

• Joule (J)

What is the effect of distance on sound intensity?

• As distance from the sound source increases, the intensity of the sound decreases.

• The intensity of sound remains constant regardless of distance.

• Sound intensity increases as you move away from the source.

• Distance has no effect on sound intensity.

What is a sound wave's wavelength?

• The speed at which sound travels through a medium.

• The frequency of the sound wave.

• The distance between successive crests or troughs of a wave.

• The amplitude of the sound wave.

Define sound waves.

• Vibrations that travel through air, water, or solid materials and can be heard when they reach a person's or animal's ear.

• A type of wave that can only travel through air and is not audible to humans.

• A phenomenon that occurs when light waves interact with sound waves.

• A series of electrical signals that are transmitted through wires.

What does high amplitude indicate about a sound?

• Quieter sounds

• Louder sounds

• Higher pitch sounds

• Lower pitch sounds

What is an example of a high amplitude sound?

• A whisper in a quiet room.

• A loud concert or a thunderclap.

• A soft rustling of leaves.

• A gentle breeze.
