What are the 3 types of spectrum's?

Answer 1

The three different types of spectra are:

Emission spectra are produced by hot, thin gases in which the atoms do not experience many collisions (because of the low density). The emission lines correspond to photons of discrete energies that are emitted when excited atomic states in the gas make transitions back to lower-lying levels.

A continuous spectrum results when the gas pressures are higher. Generally, solids, liquids, or dense gases emit light at all wavelengths when heated.

An absorption spectrum occurs when light from a hot, dense object passes through a cold, dilute gas and atoms in the gas absorb at characteristic frequencies; since the re-emitted light is unlikely to be emitted in the same direction as the absorbed photon, this gives rise to dark lines (absence of light) in the spectrum.

Answer 2

Radio: Yes, this is the same kind of energy that radio stations emit into the air for your boom box to capture and turn into your favorite Mozart, Madonna, or Justin Timberlake tunes. But radio waves are also emitted by other things ... such as stars and gases in space. You may not be able to dance to what these objects emit, but you can use it to learn what they are made of. Microwaves: They will cook your popcorn in just a few minutes! Microwaves in space are used by astronomers to learn about the structure of nearby galaxies, and our own Milky Way! Infrared: Our skin emits infrared light, which is why we can be seen in the dark by someone using night vision goggles. In space, IR light maps the dust between stars.
Visible: Yes, this is the part that our eyes see. Visible radiation is emitted by everything from fireflies to light bulbs to stars ... also by fast-moving particles hitting other particles.
Ultraviolet: We know that the Sun is a source of ultraviolet (or UV) radiation, because it is the UV rays that cause our skin to burn! Stars and other "hot" objects in space emit UV radiation. X-rays: Your doctor uses them to look at your bones and your dentist to look at your teeth. Hot gases in the Universe also emit X-rays . Gamma-rays: Radioactive materials (some natural and others made by man in things like nuclear power plants) can emit gamma-rays. Big particle accelerators that scientists use to help them understand what matter is made of can sometimes generate gamma-rays. But the biggest gamma-ray generator of all is the Universe! It makes gamma radiation in all kinds of ways.

Answer 3

Ultraviolet rays and infrared rays, but I don't know a third. (The human eye can only see optical or visible light. Light comes in many other colors -- radio, infrared, ultraviolet, X-ray and gamma-ray.) kg

Answer 4

The three types of spectra are continuous, emission, and absorption spectra. Continuous spectra show a continuous range of wavelengths without any breaks. Emission spectra display bright lines at specific wavelengths, indicating the emission of light by excited atoms. Absorption spectra exhibit dark lines at certain wavelengths, revealing the absorption of light by atoms.

Answer 6

Light spectra can be split into more than three types, but you could say three types are ultraviolet, visible, and infrared.

Answer 7

Radio waves, Microwaves, Infrared waves, Visible Spectrum (red, orange, yellow, green, blue, violet), Ultra Violet, X-Rays, Gamma Rays

Answer 9

There is only one electromagnetic spectrum. What you consider to be spectra are just different sections of it.
