  • What is the electromagnetic spectrum?
    It is a continuum of electromagnetic radiation containing all wavelengths and frequencies.
  • How does wavelength change as you move from radio waves to gamma rays on the electromagnetic spectrum?
    The wavelength decreases as you move from radio waves to gamma rays.
  • How does frequency change as you move from radio waves to gamma rays?
    The frequency increases as you move from radio waves to gamma rays.
  • What is the mnemonic to remember the order of the electromagnetic spectrum?
    The mnemonic is 'Large Root Martians Invented Very Unusual X-ray Guns.'
  • What does each word in the mnemonic 'Large Root Martians Invented Very Unusual X-ray Guns' represent?
    'Large' is long radio waves, 'Root' is radio waves, 'Martians' is microwaves, 'Invented' is infrared, 'Very' is visible light, 'Unusual' is ultraviolet, 'X-ray' is X-rays, and 'Guns' is gamma rays.
  • Which part of the electromagnetic spectrum can humans see without instruments?
    Humans can see the visible light spectrum without instruments.
  • What is the wavelength range of the visible light spectrum?
    It ranges from 700 nanometers (red) to 380 nanometers (violet).
  • Which color in the visible spectrum has the longest wavelength?
    Red light has the longest wavelength in the visible spectrum.
  • Which color in the visible spectrum has the shortest wavelength?
    Violet light has the shortest wavelength in the visible spectrum.
  • What mnemonic helps remember the order of colors in the visible spectrum?
    The mnemonic is 'ROY G BIV' for Red, Orange, Yellow, Green, Blue, Indigo, Violet.
  • What type of electromagnetic radiation is found just below the red end of the visible spectrum?
    Infrared radiation is found just below the red end of the visible spectrum.
  • What type of electromagnetic radiation is found just above the violet end of the visible spectrum?
    Ultraviolet radiation is found just above the violet end of the visible spectrum.
  • Which type of electromagnetic wave has the highest frequency?
    Gamma rays have the highest frequency.
  • Which type of electromagnetic wave has the longest wavelength?
    Long radio waves have the longest wavelength.
  • Why is the visible light spectrum important to humans?
    It is important because it is the part of the electromagnetic spectrum that we can see with our eyes without instruments.
