Telescopes And Electromagnetic Waves

You can see features of the universe using other types of electromagnetic energy that your eyes alone cannot see.

Radio waves have the longest wavelength. They can be longer than a football field.

Reflecting telescopes use mirrors to magnify and focus visible light from distant objects like stars.

Refracting Telescopes use lens to magnify and focus visible light from distant objects like stars.

CCD arrays capture electromagnetic waves and convert them to pixels of data.

Gamma rays have the shortest wavelength. They are so short that they can pass between parts of an atom.

Gamma rays are usually called radiation.

Light waves or light are the only electromagnetic waves you can see.

CCD arrays allow scientists to 'see' ultraviolet light and infrared light as well as visible light.

Radio Telescopes Capture radio waves and use an amplifier to tune into them and a computer to make an image from the waves.

Radio waves can be used to figure out the types of atoms and compounds that an object in space is made of.

A bunch of telescopes working together as one giant telescope is an telescope array.

Things that give off huge amounts of energy can be seen with X rays, including black holes, neutron stars, and supernova explosions.

A stars temperature matches its color. Blue stars are the hottest stars and red stars are the 'coolest' stars.

You can feel infrared waves as heat.
