• andre marie ampere
• James Clerk Maxwell found out about that the speed of light is highly identical to the speed of an electromagnetic wave
• Scientist?


  direct relationship of magnetism and electricity
• Andrei Marie Ampere found out that the ? 


  a wire carrying electric current can attract and repel one another wire
• heinrich hertz ?


  found out that the velocity of a wave can be measured by its wave cycle(frequency)
• michael faraday?


  found out that mechanical energy can be converted into electrical energy using a device called generator
• identify the parts hehe

  A) crest

  B) wavelength

  C) equilibrium

  D) trough

  E) amplitude

  
• name the seven wave in the electromagnetic spectrum: radio, microwave, infrared, visible light, ultraviolet, x-ray, gamma ray
• identify hehe

  A) compression

  B) rarefraction

  C) compression

  D) wavelength

  
• PROPERTIES OF EM WAVES:

  1. em waves are distrubances in a field rather than a medium
  2. electric and magnetic fields move perpendicular to each other and to the direction of propagating ave or a transverse wave
  3. EM waves an be reflected or refracted
• Properties pa rin hehe

  4. EM WAVES CAN BE EMITTED OR ABSORBED
• 5 MOST EM AWVES ARE INVISIBLE BUT DETECTABLE
• 6. EM WAVES CAN BE BLOCKED BY SOME MATERIALS
• 7. EM WAVES CAN BE DEFINED THROUGH THE AMOUNT OF ENERGY CARRIED BY PHOTONS
• 8. EM WAVES CAN TRAVEL THROUGH A MEDIUM AND VACUUM AT A CONSTANT SPEED WHICH IS THE SPEED OF LIGHT 300,000,000 OR 3X10^8 m/s
• 9. EM WAVES ARE CLASSIFIED ACCORDING TO FREQUENCY AND WAVELENGTH
• 10. THE CONTINUUM OR RANGE OF AN EM WAVES CLASSIFIED ACCORDING TO FREQUENCY AND WAVELENGTH IS CALLED THE ELECTROMAGNETIC SPECTRUM
• v=λ*f is used when looking for velocity
• $λ=$$v/f$


  is used when looking for the wavelength
• $f=$$v/ λ$

  is when looking for the frequency
