  • 1

    is a disturbance that transfers energy

    Wave

  • 2

    The energy of a wave is _____ to its frequency

    directly proportional

  • 3

    The energy of a wave is ____ to its wavelength

    inversely proportional

  • 4

    waves produced by vibrating electrons.

    Electromagnetic

  • 5

    The EM spectrum consists of

    radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and Gamma rays

  • 6

    Can travel through a medium and a vacuum. Has a speed of 3.0 x 108 m/s in vacuum.

    EM wave

  • 7

    Have an electric field that travels ____ with the magnetic field.

    perpendicular

  • 8

    Are mostly undetectable, only ____ can be seen by humans.

    visible light

  • 9

    a Scottish scientist developed a scientific theory to explain electromagnetic waves. He noticed that electrical fields and magnetic fields can couple together to form electromagnetic waves. He summarized this relationship between electricity and magnetism by developing equations, "Maxwell's Equations.”

    James Clerk Maxwell

  • 10

    a German physicist who showed that Maxwell's theory of electromagnetism was correct and that light and heat are electromagnetic radiations. He applied these theories to the production and reception of radio waves. The unit of frequency of a radio wave -- one cycle per second -- is named the hertz, in honor of ____

    Heinrich Hertz

  • 11

    discovered electromagnetic induction, has contributions on electrical engineering and electrochemistry, he was responsible for introducing the concept of field in physics to describe electromagnetic interaction.

    Michael Faraday (1791-1867)

  • 12

    French physicist who founded and named the science of electrodynamics, now known as electromagnetism. He immediately set to work developing a mathematical and physical theory to understand the relationship between electricity and magnetism. He showed that two parallel wires carrying electric currents repel or attract each other, depending on whether the currents flow in the same or opposite directions, respectively.

    André-Marie Ampère (1775-1836)

  • 13

    was Danish physicist and chemist who discovered that electric currents create magnetic fields, which the first connection was found between electricity and magnetism.

    Hans Christian Oersted (1777 –1851)
