Step-by-step explanation:
A wave is a disturbance or variation that travels through a medium or space, transferring energy from one point to another without the overall movement of matter. Waves can take various forms, such as water waves, sound waves, or light waves. They are characterized by properties like wavelength, frequency, amplitude, and speed.
An electromagnetic wave is a type of wave that consists of synchronized oscillations of electric and magnetic fields, perpendicular to each other and perpendicular to the direction of wave propagation. These waves do not require a medium to travel through and can propagate through a vacuum. Electromagnetic waves include a wide range of frequencies and wavelengths, forming the electromagnetic spectrum. This spectrum includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Each type of electromagnetic wave has its own unique properties and applications.
