Why are electromagnetic waves used to detect supernovas instead of sound waves?

Back

Electromagnetic waves can travel in vacuums, while sound waves cannot.

Front

What is the speed of light in a vacuum?

Back

Approximately 299,792 kilometers per second (km/s).

Front

What is the relationship between wavelength and frequency?

Back

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