VOCABULARY

Electromagnetic spectrum

• The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation.

Photon

• The definition of a photon is a particle that has energy and movement; but, it does not have mass or electrical charge.

Spectroscopy

• the study of spectra by use of the spectroscope

Continuous spectrum

• A spectrum appearing uninterrupted by lines or bands across a range of wavelengths.

Absorption spectrum

• a spectrum with a pattern of dark bands or lines created when light passes through a gas or liquid into a spectroscope: the chemical elements of the gas or liquid absorb specific wavelengths of light creating a unique pattern which can be used to analyze the gas or liquid chemically

Emission spectrum

• The spectrum of bright lines, bands, or continuous radiation characteristic of and determined by a specific emitting substance subjected to a specific kind of excitation.

Doppler effect

• The Doppler effect is defined as a noticeable change in the frequency of sound, light or water waves as the source and the observer move.

Photosphere

• the visible surface of the sun

Chromosphere

• the pinkish, glowing region around a star, esp. the sun, between the hot, dense photosphere and the much hotter, tenuous corona

Corona

• the layer of ionized gas surrounding the sun, characterized by an extremely low density, an extremely high temperature, and a constantly changing shape extending great distances from the sun: clearly visible during a total solar eclipse

Solar wind

• streams of ionized gas particles constantly emitted by the sun in all directions at speeds of c. 300 to 1,000 km per second (c. 186 to 620 mi per second)

Sunspot

• Any of the relatively cool dark spots appearing periodically in groups on the surface of the sun that are associated with strong magnetic fields.

Prominence

• the state or quality of being prominent

Solar flare

• a sudden, short-lived increase of intensity in the light of the sun, usually near sunspots, often accompanied by a large increase in cosmic rays, X-rays, etc. and by resultant magnetic storms

Aurora

• Meteorologically, an aurora is the result of charged particles colliding, creating bright lights in the sky.

Nuclear fusion

• Nuclear fusion is when two or more lightweight atoms join together to form one heavier nucleus, with any energy released due to the conversion being converted into nuclear energy.
