Sound Waves

Can sound waves travel through solids?

• Yes, sound waves can travel through solids, liquids, and gases.

• No, sound waves can only travel through gases.

• Yes, but only at very high frequencies.

• No, sound waves cannot travel through any medium.

What is an example of a longitudinal wave?

• Light waves

• Water waves

• Sound waves

• Radio waves

How does sound travel in a vacuum?

• Sound travels freely in a vacuum.

• Sound cannot travel in a vacuum because there are no molecules to vibrate.

• Sound travels faster in a vacuum than in air.

• Sound can travel in a vacuum if it is amplified.

What is the difference between mechanical and electromagnetic waves?

• Mechanical waves can travel through a vacuum, while electromagnetic waves cannot.

• Mechanical waves require a medium to travel, while electromagnetic waves do not.

• Mechanical waves are faster than electromagnetic waves.

• Mechanical waves are a type of electromagnetic wave.

What is the relationship between frequency and pitch?

• Higher frequency sound waves produce higher pitch sounds.

• Higher frequency sound waves produce lower pitch sounds.

• Lower frequency sound waves produce higher pitch sounds.

• Frequency has no effect on pitch.

What happens to sound waves as they travel through different mediums?

• They disappear completely.

• They can change speed and direction when they travel through different mediums.

• They become inaudible.

• They only travel faster in denser mediums.

What is resonance in sound waves?

• Resonance occurs when an object vibrates at its natural frequency due to an external sound.

• Resonance is the phenomenon where sound waves are absorbed by materials.

• Resonance happens when sound waves travel faster than the speed of light.

• Resonance is the reflection of sound waves off a surface.

What does it mean for a wave to be longitudinal?

• In longitudinal waves, the disturbance of the wave travels in the same direction as the wave.

• Longitudinal waves are characterized by their high frequency.

• Longitudinal waves can only travel through solids.

• Longitudinal waves have a wavelength that is always constant.

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

• 300 meters per second

• 343 meters per second

• 400 meters per second

• 350 meters per second

What is a characteristic of mechanical waves?

• Mechanical waves can travel through a vacuum without a medium.

• Mechanical waves require a medium (solid, liquid, or gas) to travel.

• Mechanical waves are always longitudinal in nature.

• Mechanical waves can only travel through solids.
