  2. Daily Reflection • Prompt: Give 5 examples of electromagnetic waves. What is the one difference between all the electromagnetic waves? .

  3. Electromagnetic Wave • An electromagnetic wave consists of vibrating electric and magnetic field that move through space at the speed of lig____ ht

  4. What are some examples of electromagnetic waves? • Radio Waves • TV Signals • Microwaves • Infrared rays • Light • Ultraviolet rays • X-Ray

  5. How fast do electromagnetic waves travel? • It is the fastest thing in the universe • 300,000 km per second • 186,000 miles per second • It takes 8 minutes for light to travel from the sun to the earth • It takes 3 million years for light to travel from the nearest galaxy (andromeda) to the earth

  6. Electromagnetic Wavelength

  7. How do we use Radio Waves & Microwaves? • Radio & TV signals • Microwave Oven • Radar • MRI • Cell phone

  8. Using Microwaves • Why do you see sparks you put metal objects in a microwave? • Because of the build up of electrical energy in the metal • The long wave length of Microwaves can pass right through glass and plastic. That is why microwaves do not heat glass and plastic containers.

  9. Cell phone towers • These towers are placed 1 -2 miles apart in a city • They use M______wave to communicate with cell phones • They can be used to locate the loc_______ of the caller. icro ation

  10. How do we use Infrared Rays? • Conventional Oven • Heat Lamps • Thermograms

  11. Visible Light makes up only a small part of the electromagnetic spectrum

  12. Transparent Materials • Transparent material trans_____ most of the light that strike it. mit

  13. Translucent Materials • A translucent material sca____ light as it passes through, just as smoke, fog, and clouds scatter light as it passes through the air. tters

  14. Opaque Materials • An opaque material refl_____ or absorbs all of the light that strikes it. ects
