# Physics: true or false

Doubling the amplitude of a wave will double the amount of energy the wave can transfer.
A. True

The medium determines the speed through which most mechanical waves will travel.
B. False

• Physics: true or false -

both are correct. In the first one, energy is proportional to amplitude squared.

On the second, the inertia and the bulk modulus (elasticity or compressibility) are the items that determine speed in mattter. These are physical properties of the medium.
