can anyone tell me what the speed of any e.m. wave through space and am i right in saying that they are transverse waves?
The speed of electromagnetic waves, also known as the speed of light, is approximately 299,792,458 meters per second in a vacuum. This is the maximum speed at which all electromagnetic radiation can travel in a vacuum.
The speed of electromagnetic waves is determined by the properties of the medium through which they are traveling. In a vacuum, the speed is constant and is determined by the fundamental constants of nature, such as the electric permittivity and magnetic permeability of free space.
Transverse waves are characterized by oscillations perpendicular to the direction of energy transfer, while longitudinal waves have oscillations parallel to the direction of energy transfer. Electromagnetic waves are transverse waves, meaning that their electric and magnetic fields oscillate perpendicular to the direction of propagation.
Electromagnetic radiation travels through space in the form of waves. These waves are created by the oscillation of electric and magnetic fields and do not require a medium to travel through. This is why electromagnetic waves can travel through a vacuum.
Some examples of electromagnetic radiation include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Each type of radiation has a different wavelength and frequency, which determines its properties and potential uses.
