The relationship between electromagnetic waves and matter is that the atoms and molecules that make up matter absorb and emit electromagnetic waves.

The existence of electromagnetic waves was predicted in the 1800s by British physicist James Clerk Maxwell and was proven by the experiments of German physicist Heinrich Hertz. Additionally, in the 1900s, Albert Einstein demonstrated that electromagnetic waves have particle-like properties through quantum mechanics. In quantum mechanics, light (electromagnetic waves) is treated as quantized photons. 【Trivia: The Discovery of Electromagnetic Waves and Far Infrared Rays】 ○ Electromagnetic waves around us / Electromagnetic waves from space ○ Far infrared rays are a type of electromagnetic wave ○ Electromagnetic generation from heating ○ Far infrared rays For more details, please contact us or download the catalog.

basic information

**Discovery of Electromagnetic Waves and Far Infrared Rays** ○ Electromagnetic Waves in Our Daily Lives → They are applied in everyday items such as televisions, remote controls, fluorescent lights, mobile phones, and microwave ovens. ○ Electromagnetic Waves from Space → High-energy gamma rays, X-rays, and some ultraviolet rays are absorbed by the ozone layer. → Far infrared rays longer than 25μ and some radio waves are also absorbed by the atmosphere and hardly reach the Earth's surface. → Only visible light, near-infrared rays, and radio waves with wavelengths from 1 cm to 100 m reach the Earth's surface. ○ All electromagnetic waves travel at the same speed as light → Regardless of wavelength, the propagation speed of X-rays, ultraviolet rays, visible light, infrared rays, and microwaves is constant at 300,000 km/sec. ○ There are electromagnetic waves generated by means other than electric and magnetic fields → Electromagnetic waves generated from atoms → Electromagnetic waves generated from molecules → Electromagnetic waves generated from heating ○ Electromagnetic waves and matter have an interrelationship where the atoms and molecules that make up matter absorb and emit electromagnetic waves. ● For more details, please contact us or download the catalog.
