Light and Sound Wave Review

Front

What is frequency?

Back

Frequency is the number of waves passing a point in one second, measured in Hertz (Hz).

Front

What happens when you sing?

Back

When you sing, you are causing air molecules to vibrate.

Front

What is echolocation?

Back

Echolocation is a way to locate objects by reflecting sound.

Front

What are the particles that make up light?

Back

Light is made up of particles called photons.

Front

What is wavelength?

Back

Wavelength is the distance a wave travels from crest to crest or trough to trough.

Front

What is amplitude?

Back

Amplitude is the maximum distance that a wave varies from its rest position.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is sound?

Back

Sound is a type of mechanical wave that travels through a medium (like air) by vibrating particles.

Front

What is the speed of sound in air?

Back

The speed of sound in air at room temperature is approximately 343 meters per second.

Front

What is reflection of sound?

Back

Reflection of sound occurs when sound waves bounce off a surface, creating an echo.
