The electromagnetic spectrum
The word radiation means ‘energy that is transported from one spot to another without need of direct contact between the two locations’. Light in each of these colours carries a different amount of energy: gamma rays are the most energetic, and radio is the least. Thus, when we observe

The Structure of the Sun
cesar.esa.intagainst sunspot activity. A reliable connection is assumed between sunspot activity , the magnetic field of the Earth, and resulting solar storms, but the precise relationship is unidentified. Different methods using the geomagnetic variations that is caused by solar storms have been established to predict subsequent sunspot activity.
