Front

Why do astronomers study light?

Back

Because the only way we can interact with most things is by 'looking' at them.

Front

Define wavelength in the context of light waves.

Back

Wavelength is the distance between successive peaks of a wave.

Front

What is the relationship between frequency and wavelength in light waves?

Back

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

Front

What is the visible spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye.
