What is amplitude?

Back

Amplitude is the height of a wave, which determines the loudness of a sound.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive peaks of a wave.

Front

What is the relationship between frequency and pitch?

Back

The higher the frequency, the higher the pitch; the lower the frequency, the lower the pitch.

Front

What are light waves?

Back

Light waves are electromagnetic waves that allow us to see and are also a form of energy.

Front

What is energy?

Back

Energy is the ability to do work or cause change, and it exists in various forms, including light and sound.
