Waves Test

Front

What is a sound wave?

Back

A sound wave is a type of wave that travels through air (or other mediums) and is created by vibrating objects, allowing us to hear sounds.

Front

What does pitch refer to in sound?

Back

Pitch refers to how high or low a sound is, which is determined by the frequency of the sound wave.

Front

What is the relationship between wavelength and pitch?

Back

A high pitch sound has a short wavelength, while a low pitch sound has a long wavelength.

Front

What is an oscilloscope?

Back

An oscilloscope is a device that visually displays sound waves as graphs, showing their amplitude and frequency.

Front

How does a high sound wave look compared to a low sound wave?

Back

A high sound wave appears more compressed (shorter wavelength) and has more peaks in a given distance, while a low sound wave is more spread out (longer wavelength).

Front

What is frequency in relation to sound waves?

Back

Frequency is the number of times a wave cycles (or repeats) in one second, measured in Hertz (Hz). Higher frequency means a higher pitch.

Front

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

Back

Sound waves travel at different speeds depending on the material; they travel faster in solids than in liquids and gases.

Front

What is amplitude in sound waves?

Back

Amplitude refers to the height of the wave, which determines the loudness of the sound; higher amplitude means a louder sound.

Front

What is the difference between a longitudinal wave and a transverse wave?

Back

In a longitudinal wave, the particles of the medium move parallel to the direction of the wave, while in a transverse wave, the particles move perpendicular to the direction of the wave.

Front

Can sound travel in a vacuum?

Back

No, sound cannot travel in a vacuum because it requires a medium (like air, water, or solids) to carry the sound waves.
