Question

Which types of waves requires matter to carry energy?

electromagnetic waves only
mechanical waves only
electromagnetic and mechanical waves
longitudinal and electromagnetic waves

Answer 1

Mechanical waves only require matter to carry energy. Mechanical waves, such as sound waves and water waves, propagate through a medium (solid, liquid, or gas). In contrast, electromagnetic waves (such as light) do not require a medium and can travel through a vacuum. Therefore, the correct answer is **mechanical waves only**.
