Science - Electromagnetic Waves

Electromagnetic Spectrum

The complete range of EM waves in order of increasing frequency and decreasing wavelength.

Electric Forces

Produced by electric charges either at rest or in motion.

Magnetic Forces

Produced only by moving charges and act solely on charges in motion.

Spectrum

A range of different positions, between two extreme points:

Increasing Wavelength

Increasing Frequency

EM Radiation

created when a charged particle accelerates, causing energy to travel through space as electromagnetic waves.

Radio Waves

Essential for broadcasting and wireless communication.

Microwaves

Electromagnetic waves used for communication, radar, and heating food.

Infrared Waves

Electromagnetic waves associated with heat, used in things like thermal cameras, remote controls, and heat sensors.

Visible Light

The part of the electromagnetic spectrum that can be detected by the human eye.

Ultraviolet Rays

High-energy electromagnetic waves from sources like the Sun that can cause sunburn.

X-Rays

High-energy electromagnetic waves that can pass through soft tissue and are commonly used to create medical images.

Gamma Rays

The highest-energy electromagnetic waves, produced by nuclear reactions and some radioactive processes.
