Sound Waves

What is wavelength?

• The time it takes for one complete wave to pass a point.

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

• The speed at which a wave travels through a medium.

• The amplitude of a wave measured from the rest position.

What is the relationship between amplitude and loudness?

• Higher amplitude means a softer sound.

• Higher amplitude means a louder sound, while lower amplitude means a softer sound.

• Amplitude has no effect on loudness.

• Lower amplitude means a louder sound.

What is a sound wave?

• A type of electromagnetic wave that travels through a vacuum.

• A type of mechanical wave that travels through a medium due to vibrations.

• A type of wave that can only travel through solids.

• A type of wave that is produced by electrical signals.

What determines the pitch of a sound?

• The amplitude of the sound waves.

• The frequency of the sound waves.

• The duration of the sound waves.

• The speed of the sound waves.

What is vibration?

• A slow and steady movement of an object.

• A rapid back-and-forth motion that can occur in solids, liquids, or gases.

• A type of sound wave that travels through air.

• A constant change in temperature of a substance.

What is the starting position in a wave?

• The peak of the wave

• The trough of the wave

• The equilibrium position of a wave, where the wave would be if there were no disturbances

• The amplitude of the wave

What is the process that produces sound?

• Sound is produced when something vibrates.

• Sound is produced by electrical signals.

• Sound is produced through chemical reactions.

• Sound is produced by light waves.

What is the difference between longitudinal and transverse waves?

• In longitudinal waves, the particle movement is perpendicular to the direction of the wave, while in transverse waves, the particle movement is parallel to the direction of the wave.

• In longitudinal waves, the particle movement is parallel to the direction of the wave, while in transverse waves, the particle movement is perpendicular to the direction of the wave.

• Both longitudinal and transverse waves have particle movement that is parallel to the direction of the wave.

• Longitudinal waves are faster than transverse waves.

What is rarefaction?

• A region in a longitudinal wave where the particles are spread apart.

• A type of wave that travels through a vacuum.

• A measure of the frequency of a wave.

• A region in a transverse wave where particles are tightly packed.

What is a medium in the context of sound?

• A type of sound wave

• The substance through which sound waves travel, such as air, water, or solids.

• A measurement of sound intensity

• A device used to amplify sound
