Study Notes

Waves

Waves transfer energy
Vibrations produce waves
Sound waves require matter to travel
Sound waves transfer energy from particle to particle

Electromagnetic Waves

EM waves are transverse waves
EM waves are produced by vibrating charged particles
EM waves transfer electrical and magnetic energy
EM waves don't require matter to travel
EM waves can travel through a vacuum
All EM waves travel at the speed of light in a vacuum (300,000,000 m/s)
Light from the sun takes roughly 8 minutes to reach Earth
EM waves travel slower in mediums like air

Electromagnetic Spectrum

The electromagnetic spectrum is a complete range of EM waves
The spectrum is divided into 7 regions: radio waves, infrared waves, visible light, ultraviolet rays, X-rays, and gamma rays
The regions are ordered by increasing energy and decreasing wavelength
Visible light (or simply "light") is the portion of the EM spectrum that human eyes can detect
