Why cant sound travel through space?

• Sound cannot travel through space because there is no medium (like air) for it to propagate.
• Sound can travel through space if it is loud enough.
• It doesn't have enough frequency

• Sound can travel through space because it is a form of light.

What wave property do we use to categorize different forms of light on the EM spectrum?

• Amplitude
• Wavelength
• Speed
• Index of Refraction

• Malus's Law

What controls the pitch of the sound wave? This is whether a sound wave sounds low(bass) or high(treble).

• Amplitude of the sound wave
• Duration of the sound wave
