U7.W4.MC Sound, Waves, Communication & Technology

Front

What are sound waves?

Back

Sound waves are vibrations that travel through a medium (like air, water, or solids) and can be heard when they reach our ears.

Front

Do sound waves require a medium to travel?

Back

Yes, sound waves require particles in a medium (like air or water) to travel.

Front

Can sound be heard in space?

Back

No, sound cannot be heard in space because there are no particles to carry the sound waves.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the particles move up and down perpendicular to the direction the wave travels.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave where the particles move back and forth in the same direction as the wave travels.

Front

What happens to the amplitude of a wave when more energy is added?

Back

The amplitude of the wave increases when more energy is added.

Front

What is amplitude in a wave?

Back

Amplitude is the height of the wave from its rest position to its crest or trough, indicating the energy of the wave.

Front

What is a medium in the context of sound waves?

Back

A medium is a substance (solid, liquid, or gas) through which sound waves travel.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency sound waves produce higher pitch sounds, while lower frequency sound waves produce lower pitch sounds.

Front

What is an example of a transverse wave?

Back

An example of a transverse wave is a wave on a string or water wave.
