What is sound?

Back

Sound is a type of energy made by vibrations that travels through a medium (like air, water, or solids) and can be heard when it reaches a person's or animal's ear.

What is amplitude in a sound wave?

Back

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

What is frequency in a sound wave?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz). It determines the pitch of the sound.

Front

What is pitch?

Back

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

What is wavelength?

Back

Wavelength is the distance between two consecutive peaks or troughs in a wave. It is inversely related to frequency.

What is the relationship between frequency and pitch?

Back

Higher frequency results in a higher pitch, while lower frequency results in a lower pitch.

Front

What is the role of a medium in sound transmission?

Back

A medium (like air, water, or solids) is necessary for sound to travel, as sound waves are created by vibrating particles in the medium.

What happens to sound as it travels through different mediums?

Back

Sound travels at different speeds depending on the medium; it travels fastest in solids, slower in liquids, and slowest in gases.

What is the peak of a sound wave?

Back

The peak is the highest point of a wave, representing the maximum displacement of the wave from its rest position.

What is the trough of a sound wave?

Back

The trough is the lowest point of a wave, representing the minimum displacement of the wave from its rest position.
