EMhullámokra

EMhullámokra, or electromagnetic waves, are a fundamental phenomenon in physics. They are a form of energy that propagates through space, and they are characterized by oscillating electric and magnetic fields that are perpendicular to each other and to the direction of propagation. These waves do not require a medium to travel and can thus traverse the vacuum of space.

The electromagnetic spectrum encompasses a wide range of these waves, differing in their frequency and wavelength. This spectrum includes, in order of increasing frequency, radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Each part of the spectrum has distinct properties and applications. For example, radio waves are used for communication, visible light allows us to see, and X-rays are used in medical imaging.

The speed at which all electromagnetic waves travel in a vacuum is a universal constant known as the speed of light, approximately 299,792 kilometers per second. When EMhullámokra travel through a medium, their speed is reduced. The interaction of EMhullámokra with matter is responsible for many observable phenomena, such as reflection, refraction, absorption, and diffraction. Their study is crucial for understanding a vast array of physical processes and technologies.
