    This contains the highest energy of all the types of radiation in the EM spectrum.

    Gamma Rays

  • 7

    These are used for long-distance communications.

    Low Frequency Waves

  • 8

    This have-sub-bands with different wavelengths and uses, such as L, S, C, and K.

    Microwaves

  • 9

    This exposure happens when you get high amounts of radiation exposure over a very short period of time, such as a person undergoing cancer treatment.

    Acute Exposure

  • 10

    These are transverse oscillating waves composed of electric and magnetic fields.

    Electromagnetic Wave

  • 11

    These are used international broadcasting stations.

    High Frequency Waves

    Extremely Low Frequency Waves, Very Low Frequency Waves, Low Frequency Waves, Medium Frequency Waves, High Frequency Waves, Very High Frequency Waves, Ultra High Frequency Waves

  • 14

    This wave is used for remote sensing.

    Infrared Wave

  • 15

    This exposure occurs when a person is exposed to a small amount of radiation over a long period of time.

    Chronic Exposure

  • 16

    This wave can be seen between UV Waves and Gamma Rays.

    X-ray

  • 17

    These are form of electromagnetic radiation with very high energy, which can cause significant changes at the cellular level.

    Gamma Rays

  • 18

    These waves are used for military communications with submarines.

    Very Low Frequency Waves

  • 19

    Where can we found the range of all types of EM radiation.

    Electromagnetic Spectrum

  • 20

    This waves have a wavelengths ranging from 1 cm to 1 km, with frequencies ranging from 30 gigahertz (GHz) to 300 kilohertz (kHz).

    Radio Waves

  • 21

    A disturbance in the electric and magnetic field that propagates through space, transferring energy from one point to another.

    Electromagnetic Wave

  • 22

    What are the two types of Extremely Low Frequency Waves?

    Naturally Occuring Elf, Artificial Elf

  • 23

    This radiation includes microwaves, radio waves IR, Visible Light, and UV

    Non-ionizing Radiation

  • 24

    When this wave is emitted, certain patterns of lines and colors appear.

    Visible Light

  • 25

    These are used in digital audio broadcasting and mobile radio systems.

    Very High Frequency Waves

  • 26

    This type of waves can be naturally generated in the atmosphere.

    Radio Waves

  • 27

    This band is also called as the myriameter band.

    Very Low Frequency Waves

  • 28

    This wave is used for thermal imaging

    Infrared Wave

  • 29

    In this wave, the electric field is perpendicular to the magnetic field.

    Electromagnetic Wave

  • 30

    This can be used to examine most areas of the body.

    X-ray

  • 31

    These signals are transmitted by an antenna to a satellite which amplifies and re-transmits the signal to an antenna in other parts of the world.

    Microwave Signals

  • 32

    Has a frequency ranging from 300 MHz to 3 GHz and wavelengths ranging from 10 cm to 1 m.

    Ultra High Frequency Waves

  • 33

    They're mainly used to look at the bones and joints, although they're sometimes used to detect problems affecting soft tissue, such as internal organs.

    X-ray
