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
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
Radiation from Space • Radio waves • Microwaves • Infrared radiation • Visible light • Ultraviolet radiation • X rays • Gamma rays 4. electromagnetic radiation
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
Radiation from Space All electromagnetic waves travel at 300,000 km/s 7. Speed of Light
