  1. Radiation from Space Electromagnetic Waves textbook page 214

  2. Radiation from Space Radiation is energy transmitted from one place to another by electromagnetic waves 1. What is radiation? 2. What are electromagneticwaves? A wave of energy consisting of electric and magnetic fields, oscillating at right angles to each other. link

  3. Radiation from Space Mechanical waves are caused by a disturbance or vibration in matter, whether solid, gas, liquid, or plasma. 3. What are mechanical waves? Link 2 require a medium do not require a medium transfer energy travels through water and air can travel through a medium Electromagnetic Mechanical

  4. Radiation from Space • Radio waves • Microwaves • Infrared radiation • Visible light • Ultraviolet radiation • X rays • Gamma rays 4. electromagnetic radiation

  5. Radiation from Space • Electromagnetic radiation arranged by wavelength • They differ in their • frequencies • The shorter the • wavelength the higher the • frequency 5. Electromagnetic spectrum 6. frequency The number of wave crests that pass a point per unit of time

  6. Radiation from Space All electromagnetic waves travel at 300,000 km/s 7. Speed of Light
