B Forms of Energy: Sound

Sound is a type of energy that travels in waves and can be heard when it reaches our ears.

Sound travels in waves through different materials like air, water, and solids.

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

A wave pattern is how sound moves in waves, creating vibrations that we can hear.

A high-pitched sound is a sound that has a high frequency, like a whistle or a bird chirping.

A low-pitched sound is a sound that has a low frequency, like a drum or a bass guitar.

Sound travels through air by vibrating air particles, which pass the sound waves along.

Sound travels faster in water than in air because water particles are closer together.

There is no sound in space because there is no air or matter for sound waves to travel through.

A sound is louder when the vibrations are stronger, creating more energy.
