Electromagnetic Waves and Their Applications

Light waves are a form of energy consisting of tiny particles called photons.

The electromagnetic spectrum is a range of different types of light waves, categorized by their wavelength and frequency.

Radio waves are the longest waves in the electromagnetic spectrum and are used for communication, such as broadcasting radio signals and transmitting data.

Microwaves are a type of electromagnetic wave that generate heat and are used in microwave ovens and communication technologies.

Infrared waves are categorized as near or far. Near infrared waves transmit data, while far infrared waves create heat.

Visible light is the portion of the electromagnetic spectrum that is detectable by the human eye.

Ultraviolet (UV) waves are just beyond violet light on the electromagnetic spectrum. They come from the sun and are beneficial for vitamin D production but are also damaging to the skin.

X-rays are a type of high-energy electromagnetic wave that can penetrate human tissue, allowing doctors to see the inside of the body.

Gamma rays are the shortest and most energetic waves in the electromagnetic spectrum. They have medical and industrial applications, including cancer treatment and food preservation.

Visible light waves are the only type of electromagnetic waves that humans can see. This portion of the spectrum contains all the colors we perceive in the world, from red to violet.
