Sound and light waves

Front

What is the medium in the context of sound waves?

Back

The medium is the substance through which sound waves travel, such as air, water, or solids.

Front

Define wavelength in sound waves.

Back

Wavelength is the distance between one point on a compression and the corresponding point on the next compression in a sound wave.

Front

How does frequency affect pitch?

Back

As frequency increases, pitch also increases.

Front

What is a compression in a longitudinal wave?

Back

A compression is a region in a longitudinal wave where the particles are closest together.

Front

What is a transverse wave?

Back

A transverse wave occurs when the disturbance is at a right angle to the direction the wave is moving, such as heat and light waves.

Front

What is a rarefaction in a sound wave?

Back

A rarefaction is a region in a longitudinal wave where the particles are spread apart.

Front

What is the relationship between frequency and wavelength?

Back

As frequency increases, wavelength decreases, and vice versa.

Front

What is the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature (20°C) is approximately 343 meters per second.

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, they move perpendicular to the direction of the wave.

Front

What is the amplitude of a wave?

Back

Amplitude is the maximum distance that the particles of a medium move from their rest position when a wave passes through.
