Electromagnetic Spectrum

Cards (22)

  • The electromagnetic spectrum is the range of all possible wavelengths or frequencies of electromagnetic radiation.
  • Radio waves have the longest wavelengths and lowest frequencies, while gamma rays have the shortest wavelengths and highest frequencies.
  • Electromagnetic waves are transverse waves that do not require a medium to propagate, unlike sound waves which need a solid material as their medium.
  • Radio waves have the longest wavelengths and lowest energies, while gamma rays have the shortest wavelengths and highest energies.
  • Electromagnetic waves are transverse waves that do not require a medium to travel through, unlike sound waves which need air particles to vibrate.
  • Infrared (IR) radiation has longer wavelengths than visible light but shorter wavelengths than microwaves.
  • Waves can be described by their frequency (number of oscillations per second) and amplitude (height of wave).
  • Microwave radiation has longer wavelengths than IR but shorter wavelengths than radio waves.
  • Frequency is measured in Hertz (Hz), with one cycle being equal to one hertz.
  • Visible light has shorter wavelengths than IR radiation but longer wavelengths than UV radiation.
  • Ultraviolet (UV) radiation has shorter wavelengths than visible light but longer wavelengths than X-rays.
  • X-ray radiation has shorter wavelengths than UV radiation but longer wavelengths than gamma rays.
  • X-rays have higher energy levels compared to ultraviolet (UV) radiation.
  • Ultraviolet (UV) radiation has lower energy levels compared to X-rays.
  • Visible light has a wider range of colors compared to UV radiation.
  • The speed of electromagnetic waves depends on the properties of the material they pass through.
  • Ultraviolet (UV) radiation has higher energy than visible light but lower energy than X-rays.
  • The electromagnetic spectrum includes all types of EM waves, including X-rays, gamma rays, ultraviolet (UV) radiation, visible light, infrared (IR) radiation, microwaves, and radio waves.
  • Gamma ray radiation has the shortest wavelengths and highest energy levels among all forms of EM radiation.
  • Gamma rays are the most energetic form of electromagnetic radiation, followed by x-rays, then ultraviolet (UV) radiation.
  • The human eye can only detect visible light, which includes red, orange, yellow, green, blue, indigo, and violet colors.
  • Infrared radiation is less energetic than visible light, while visible light is less energetic than ultraviolet (UV) radiation.
