Let’s compare and contrast!

Explore the distinctions between mechanical and electromagnetic waves in this comprehensive overview. Mechanical waves rely on a medium to travel and encompass phenomena like sound and vibrations. In contrast, electromagnetic waves can move through a vacuum and include radio waves, visible light, and X-rays. Discover the characteristics of longitudinal and transverse waves, compare their energy propagation speeds, and understand their effects on our experiences—such as hearing sounds or seeing light.
