Bbc: Gcse Bitesize: Why Do Scientists Think That Light and Sound Are Waves?

Curated by ACT

Light travels as transverse waves and can travel through a vacuum. Sound travels as longitudinal waves and needs to travel through a solid, liquid or gas. Read about the properties of light and of sound, and learn the differences between these two types of waves. Take a quiz at the end to check your understanding.
