True/False

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

True

Yes, true.

False.

The correct statement is that the medium affects the speed at which mechanical waves travel. The speed of a mechanical wave is primarily determined by the properties of the medium it travels through. Different materials have different densities and elastic properties, which can affect the speed of a wave passing through them. For example, sound waves travel faster through solids than through liquids or gases because solids are more dense and have a higher elastic modulus. Additionally, the temperature and pressure of the medium can also influence the speed of sound waves.
