Electromagnetic Spectrum

Amplitude modulation

A method of transmitting information by changing the amplitude of a wave. Amplitude modulation is a technique used in radio broadcasting where the strength amplitude of a radio wave is varied to encode sound information.

Electromagnetic wave

A wave of electric and magnetic energy that can travel through matter or a vacuum, like X-rays. Electromagnetic waves are invisible waves, like light or radio waves, that carry energy through space.

Frequency modulation

A method of transmitting information by changing the frequency of a wave. Frequency modulation. Frequency modulation is a way to send signals by varying the frequency of a carrier wave based on the information being sent.

Gamma ray

Electromagnetic wave of the shortest wavelength and highest frequency gamma ray. Gamma rays are incredibly powerful bursts of energy that come from the nuclei of atoms and are used in medical treatments and scientific research.

Microwave

Electromagnetic radio waves with wavelengths between 1 mm and 1 m. Microwave. Microwaves are a type of electromagnetic radiation used for cooking food and transmitting information like Wi-Fi signals.

Radio waves

Electromagnetic waves with the longest wavelengths and the lowest frequencies radio waves. Radio waves are invisible energy waves used for communication.

Ultraviolet wave

An electromagnetic wave with shorter wavelength but higher frequency than visible light. Ultraviolet wave. Ultraviolet waves are invisible rays from the sun that can cause sunburn and are used in sterilization.

Visible light

Electromagnetic waves that humans can see visible light. Visible light is the part of the electromagnetic spectrum that our eyes can detect, allowing us to see colors and objects.

X-ray

A high-energy electromagnetic wave, it has shorter wavelength but higher frequency than UV. X-ray. X-rays are a type of radiation that can pass through most objects, including the body, and are commonly used to create images of bones and internal organs.
