EM Waves

  • The electromagnetic spectrum is the range of all types of electromagnetic radiation, ordered by frequency and wavelength.
  • EM Waves
  • radio waves have the longest wavelength among the different types of electromagnetic radiation in the spectrum.
  • The electromagnetic spectrum is ordered from lowest to highest frequency:
    1. Radio waves
    2. Microwaves
    3. Infrared
    4. Visible light
    5. Ultraviolet
    6. X-rays
    7. Gamma rays
  • As frequency increases, the wavelength decreases, meaning the waves become shorter.e.g., Radio waves have longer wavelengths and lower frequencies than gamma rays.
  • Electromagnetic radiation with short wavelengths and high energy belongs to the X-rays or Gamma rays region of the electromagnetic spectrum, which occupy the top steps of the staircase.
  • The image displays the electromagnetic spectrum, showing the different types of electromagnetic radiation arranged by their wavelength and frequency. Notice that as the wavelength decreases, the frequency increases, and vice versa. The visible light portion of the spectrum is highlighted to show its relationship to the other types, like radio waves and gamma rays.
  • X-rays have the very very short wavelengths and highest frequency among the types of electromagnetic radiation discussed, and they are used for medical imaging.
  • Frequency and wavelength are inversely related in electromagnetic radiation. As frequency increases, wavelength decreases, and vice versa. They both determine the energy of the radiation
  • All electromagnetic radiation travels at the constant speed of light.
  • as the wavelength of electromagnetic radiation decreases, the frequency and energy increase. So a wave with a very short wavelength, like this new discovery, would have higher energy than infrared waves.
  • The image displays the electromagnetic spectrum, ordering different types of radiation from long wavelengths (radio waves) to short wavelengths (gamma rays). Each type is paired with a common application and an image representing that application, like a microwave oven for microwaves or an X-ray image for X-rays. This visual representation helps clarify the relationship between wavelength and application.
