Correct vs Incorrect Understanding of Dispersion Through a Prism

Correct vs Incorrect Understanding of Dispersion Through a Prism

The map in words

  • White Light Enters Prism
    • What does the prism do?
      • WRONG belief: Prism CREATES 7 colours
        • Incorrect: Colours did not exist before
      • CORRECT understanding: Prism SEPARATES 7 colours already present
        • First Surface: Dispersion occurs here only
          • Different wavelengths refract by different amounts
            • Violet: max refractive index, max deviation
              • Second Surface: Deviation only, NO fresh dispersion
                • Spectrum formed on screen: R-O-Y-G-B-I-V top to bottom
            • Red: min refractive index, min deviation

Spectrum Chapter — Complete Concept Map

Spectrum Chapter — Complete Concept Map

The map in words

  • Spectrum
    • Deviation and Dispersion
      • Prism bends light twice
      • Total deviation = d1 + d2
      • Formula d = mu minus 1 times A
      • Violet deviates most
      • Red deviates least
    • Dispersion
      • White light splits into 7 colours
      • VIBGYOR order
      • Cause: different speeds
      • Spectrum formed
      • Dispersion at first surface only
    • Electromagnetic Spectrum
      • Gamma rays shortest wavelength
      • X-rays
      • Ultraviolet rays
      • Visible light 4000 to 8000 AU
      • Infrared rays
      • Microwaves
      • Radio waves longest wavelength
      • All travel at 3 times 10 to 8 m per s
    • Scattering
      • Rayleigh scattering law
      • I proportional to 1 over lambda 4
      • Blue scatters most
      • Red scatters least
      • Applications
        • Blue sky
        • Red sunrise sunset
        • White sky at noon
        • White clouds
        • Black sky on moon
        • Red danger signals
