Sound Energy

Front

What is sound energy?

Back

Sound energy is a type of energy produced by vibrating objects, which creates sound waves that travel through different mediums.

Front

How does sound travel?

Back

Sound travels through solids, liquids, and gases as vibrations of particles.

Front

What is pitch?

Back

Pitch is how high or low a sound is, determined by the frequency of the sound waves.

Front

What is volume?

Back

Volume refers to how loud or soft a sound is, which is related to the amplitude of the sound waves.

Front

What is an echo?

Back

An echo is a reflection of sound that arrives at the listener after a delay, caused by sound waves bouncing off hard surfaces.

Front

Can sound travel through a vacuum?

Back

No, sound cannot travel through a vacuum because there are no particles to carry the sound waves.

Front

What is the relationship between sound and matter?

Back

Sound requires matter (solid, liquid, or gas) to travel, as it is the vibration of particles that creates sound waves.

Front

What happens to sound waves when they hit a soft surface?

Back

Sound waves are absorbed by soft surfaces, which reduces the volume and prevents echoes.

Front

What is frequency?

Back

Frequency is the number of vibrations or cycles of a sound wave that occur in one second, measured in Hertz (Hz).

Front

What is the speed of sound?

Back

The speed of sound varies depending on the medium; it travels fastest in solids, slower in liquids, and slowest in gases.
