Sound Energy + Graphic Representations for MC Flashcard

Front

What is sound energy?

Back

Sound energy is a form of energy produced by vibrating objects, which creates sound waves that travel through a medium such as air, water, or solids.

Front

What is frequency in sound waves?

Back

Frequency refers to the number of vibrations or cycles per second in a sound wave, measured in Hertz (Hz). Higher frequency means a higher pitch.

Front

What is amplitude in sound waves?

Back

Amplitude is the height of the sound wave, which determines the volume or loudness of the sound. Higher amplitude means a louder sound.

Front

What is pitch in sound?

Back

Pitch is the perceived frequency of a sound; it determines how high or low a sound seems to a listener.

Front

How does sound travel?

Back

Sound travels in waves through different mediums (air, water, solids) by causing particles in the medium to vibrate.

Front

What is the relationship between amplitude and volume?

Back

The greater the amplitude of a sound wave, the louder the sound is perceived. Volume is directly related to amplitude.

Front

What does a sound wave with a high frequency look like?

Back

A sound wave with a high frequency has closely spaced peaks and troughs, indicating rapid vibrations.

Front

What does a sound wave with a low frequency look like?

Back

A sound wave with a low frequency has widely spaced peaks and troughs, indicating slower vibrations.

Front

What is the difference between pitch and volume?

Back

Pitch refers to how high or low a sound is, while volume refers to how loud or soft a sound is.

Front

What happens to sound waves when they travel through different mediums?

Back

Sound waves can change speed and may change in frequency and amplitude when traveling through different mediums.
