  1. What is Solar Energy? Vocabulary Solar Energy - Energy received by the Earth from the sun in the form of radiation.Each form of energy is differentiated by its wavelength.

  2. Vocabulary Electromagnetic Spectrum Consists of the complete range of wavelengths of electromagnetic waves.

  3. Read page 555 Take notes on the following: • At what speed does radiation travel through space? • Illustrate the wavelength of a wave? • Figure 1: This is five images of the at different .

  5. The Visible Sun Looking at the Sun in visible light reveals dark spots on its surface.

  6. The Sun in H-alpha In this specific color of red light we can see more details of the Sun’s magnetic activity.

  7. The Ultraviolet Sun From space, we can observe the Sun in ultraviolet (UV) light and see hot gas trapped in magnetic fields on the Sun.

  8. The Dynamic Sun

  9. The corona is known to be very hot because it has ions with many electrons removed from the atoms. At high enough temperatures the atoms collide with each other with such energy to eject electrons. This process is called ionization. At very high temperatures, atoms like iron can have 9 to 13 electrons ejected. Nine-times ionized iron is only produced at temperatures of 1.3 million K and 13-times ionized iron means the temperature gets up to 2.3 million K! During strong solar activity, the temperature can reach 3.6 million K and lines from 14-times ionized calcium are seen.
