Question

what is transmitted by all waves?
energy
mass
matter
sound

Explanation:

Waves are a means of energy transfer. For example, in electromagnetic waves (like light), energy is transmitted through space. In mechanical waves (such as water waves or sound waves in a medium), energy is transferred from one particle to another. Mass and matter are not transmitted by all waves. Sound is a type of mechanical wave, but not all waves are sound waves. So, the key property that all waves transmit is energy.

Answer:

energy
