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)
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)
- A decrease in wavelength is an increase in frequency (towards the violet end of the spectrum)
