Light Waves

Front

What is a light wave?

Back

A light wave is a type of electromagnetic wave that is visible to the human eye.

Front

Why is a light wave not considered a mechanical wave?

Back

A light wave travels through the vacuum of space.

Front

What is the main difference between electromagnetic waves and mechanical waves?

Back

An electromagnetic wave can travel through a vacuum, but a mechanical wave cannot.

Front

What type of wave is a light wave classified as?

Back

A light wave is classified as a transverse wave.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second.

Front

What is frequency in the context of waves?

Back

Frequency is the number of waves that pass a point in one second, measured in hertz (Hz).

Front

What is the wavelength of a wave?

Back

Wavelength is the distance between two consecutive peaks or troughs in a wave.

Front

What is the relationship between frequency and wavelength?

Back

The frequency and wavelength of a wave are inversely related; as frequency increases, wavelength decreases.

Front

What is an example of a mechanical wave?

Back

Sound waves are an example of mechanical waves.

Front

What is an example of an electromagnetic wave?

Back

Light waves are an example of electromagnetic waves.
