Question

mechanical waves can be transverse or longitudinal. which of the following is the only medium a transverse mechanical wave can travel through? a) solid aluminum b) helium gas c) liquid water d) outer space

Explanation:

Transverse mechanical waves require a medium with shear modulus. Solids have this property. Gases and liquids lack the ability to support shear forces well, and outer - space is a vacuum with no medium for mechanical waves. Solid aluminum is a solid medium, while helium gas is a gas, liquid water is a liquid, and outer space is a vacuum.

Answer:

A. Solid Aluminum
