\nSound waves are mechanical waves that require a medium (like air, water, or solids) to propagate. They are typically longitudinal waves in fluids.
\n<\/section>\n
\n– Electromagnetic waves are disturbances that can travel through a vacuum (like space) as well as through matter. They consist of oscillating electric and magnetic fields.
\n– Light waves, radio waves, and microwaves are all examples of electromagnetic waves, differing in their frequency and wavelength.
\n<\/section>\n
\n– The electromagnetic spectrum includes, in order of increasing frequency\/energy and decreasing wavelength: Radio waves, Microwaves, Infrared radiation, Visible light, Ultraviolet radiation, X-rays, and Gamma rays.
\n– Sound waves are caused by vibrations that create pressure variations in the medium.
