electromagnetic spectrum

The electromagnetic spectrum is the range of all types of electromagnetic radiation, which includes radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays.

X-rays have shorter wavelengths than visible light.

Gamma rays have the highest energy in the electromagnetic spectrum and are the most dangerous type of radiation.

Violet light has the shortest wavelength in the visible spectrum.

When light is reflected, it bounces off a surface instead of being absorbed or transmitted.

Light waves travel faster than sound waves.

Shorter wavelengths correspond to higher energy, while longer wavelengths correspond to lower energy.

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, ranging from approximately 400 nm (violet) to 700 nm (red).

Refraction is the bending of light as it passes from one medium to another, due to a change in its speed.

Radio waves are used for communication, including television, radio broadcasts, and mobile phones.
