    The Greenwood function correlates the position of the hair cells in the inner ear to the frequencies that stimulate their corresponding auditory neurons.Empirically derived in 1961 by Donald D. Greenwood, the relationship has shown to be constant throughout mammalian species when scaled to the appropriate cochlear spiral lengths and audible frequency ranges.

    In frequency (and thus energy), UV rays sit between the violet end of the visible spectrum and the X-ray range. The UV wavelength spectrum ranges from 399 nm to 10 nm and is divided into 3 sections: UVA, UVB, and UVC. UV is the lowest energy range energetic enough to ionize atoms, separating electrons from them, and thus causing chemical reactions.

    The use of flashing lights and sirens is colloquially known as blues and twos, which refers to the blue lights and the two-tone siren once commonplace (although most sirens now use a range of tones). In the UK, only blue lights are used to denote emergency vehicles (although other colours may be used as sidelights, stop indicators, etc.).
