6.3.4 Visible Light Spectrum

Visible Light Spectrum

  • Each colour within the visible light spectrum corresponds to a narrow band of wavelength and frequency
  • The different colours of waves correspond to different wavelengths:
    • Red has the longest wavelength (and the lowest frequency and energy)
    • Violet has the shortest wavelength (and the highest frequency and energy)

Wavelength of spectrum, IGCSE & GCSE Physics revision notes

Colours of the visible spectrum with increasing wavelength

  • Wavelength and frequency are inversely proportional, this means that:
    • An increase in wavelength is a decrease in frequency (towards the red end of the spectrum)
    • decrease in wavelength is an increase in frequency (towards the violet end of the spectrum)
