Electromagnetic Spectrum

Electromagnetic wave

Transverse wave

Electric and magnetic field move at the same time

Transmits energy

Can travel through a vacum

Travels at the same speed: 3.0 × 10^8 m/s

Radio wave

Stable and long in wavelength which allows them to travel long distance

Used for wifi signals

Microwaves

A little shorter in wavelength than radio waves

Can travel through the atmosphere

Used in satellites

Infrared waves

Used because of its short range in remotes since it doesnt need to pass through walls

Ultraviolet light

Triggers fluorescence which makes things glow

Can cause sunburns and lead to skin cancer

X-rays

Very high in energy

High frequency - low wavelength

Can penetrate soft tissues like flesh but mot harder substances like bones

Gamma rays

Highest energy electromagnetic wave

Used for killing tumors
