Concepts Of Physics MCQ Edition [Volume 1]PhysicsWave Motion and Waves on a String

Identify the mechanical wave from the options below.

Options

ASound waves
BRadio waves
CLight waves
DX-rays

Correct answer

A. Sound waves

Step-by-step solution

Mechanical waves require a material medium for their propagation. Sound waves require a medium (solid, liquid, or gas) to travel and cannot propagate through a vacuum. Hence, they are mechanical waves. Radio waves, light waves, and X-rays are electromagnetic waves, which do not require a material medium for propagation.
