Waves Flashcard

Front

What is a wavelength?

Back

The distance between two consecutive peaks or troughs in a wave.

Front

What are electromagnetic waves?

Back

Waves that can travel through a vacuum and do not require a medium, such as light waves.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

Approximately 299,792 kilometers per second (the speed of light).

Front

What is the relationship between frequency and wavelength?

Back

They are inversely related; as frequency increases, wavelength decreases.

Front

What is pitch in sound?

Back

The perceived frequency of a sound; higher frequency means higher pitch.

Front

What are the primary colors of light according to physics?

Back

Red, Green, and Blue.

Front

What color do we see when all primary colors of light are combined?

Back

White.

Front

What is amplitude in a wave?

Back

The maximum displacement of points on a wave from its rest position; it relates to the wave's energy.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through, while electromagnetic waves do not.

Front

What is a sound wave?

Back

A mechanical wave that travels through a medium (like air, water, or solids) and is perceived as sound.
