Differances between EM waves and Mechanical Waves

# data[].attributes.body
One difference is that EM Waves don't require a medium, allowing them to travel through space.
Another differance is that an EM wave is made up of two parts, the Magnetic charge and the electric charge, coming together to make one intertwining wave.

A Gamma wavelength is < 0.01 nm.  They have the highest frequency and energy because of this.  These are used to kill cancer cells and bacteria.

# data[].attributes.body
X-Ray wavelength are from 0.01 – 10 nm.  They have a lower frequency than Gamma Rays, but a longer wavelength. These are used in X-rays.

# data[].attributes.body
Ultraviolet radiation has wavelengths of 10 – 310 nm (slightly larger than an X-Ray) Causing the frequency and the energy to be lower.  Hospitals use UV lamps to sterilize surgical equipment and it can also (if given in reasonable doses) can help produce vitamin D

Visible light is the range of wavelengths from 400 – 700 nm.  These are the only light that our eyes can pick up.  The frequency and the energy are even lower than Ultra- Violet.  These are used to be able to see.  Without these you could see nothing.

Infrared wavelengths cover from 710 nm – 1 millimeter.  as Has already been seen, the higher the wavelength, the lower the frequency and energy.   These are used for infrared cameras and TV remotes.

Cooking food in a microwave, and dopplar radars.  Wavelength ranges from on millimeter to one meter

# data[].attributes.body
These waves have the longest wavelength of them all
TV signals and Am Radios

These waves are created by the vibrations in electric and magnetic fields
