Question

Which statements correctly describe the physical requirements and behaviour of an ideal mechanical wave?

G1 Physics · Accepted Answer

Mechanical waves require oscillating material particles. Elasticity supplies restoring force, and inertia allows continued motion through equilibrium. The disturbance transfers energy from one region to another, but the particles normally oscillate around equilibrium rather than undergoing a net displacement with the wave. Therefore all four statements are correct.
