Electromagnetic spectrum

a classification of all forms of radiation by wavelength and frequency; used to study components of the universe

the number of times a wave passes a certain point in a given amount of time

different colors of light emitted based on the chemical composition of the light source

a tool for observing spectral lines

a sliver of the total amount of light that surrounds us which can be seen by humans

wave of alternating electric and magnetic fields

the longest wavelengths and lowest energies of light used to map the structure of our galaxy

used by telescopes to measure the remnant glow of the Big Bang.

used by telescopes to find cool, dim stars, slicing through interstellar dust bands, and even measuring the temperatures of planets in other solar systems

or UV light can give you a sunburn; used to hunt out the most energetic of stars and identify regions of star birth

come from exotic neutron stars, the vortex of superheated material spiraling around a black hole, or diffuse clouds of gas in galactic clusters that are heated to many millions of degrees

the shortest wavelength of light and deadly to humans – show violent supernova explosions, cosmic radioactive decay, and even the destruction of antimatter; emit when a star explodes and creates a black hole

Electromagnetic Radiation

energy that travels through space in the form of waves

Electromagnetic Spectrum

the complete range of electromagnetic radiation from the shortest waves, gamma rays, to the longest radio waves

Electromagnetic Waves

transverse waves that transfer electrical and magnetic energy

an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum

the distance between two points on adjacent waves that have the same phase

Electromagnetic Spectrum

used by scientists to describe the entire range of light that exists. From radio waves to gamma rays, most of the light in the universe is, in fact, invisible to us!
