WebThe relationship between light intensity – at these low light intensities – is linear. Be careful – the x-axis is values of \(\frac{1}{d^{2}}\) . It is not of light intensity. The lux (symbol: lx) is the unit of illuminance, or luminous flux per unit area, in the International System of Units (SI). It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface. It is analogous to the radiometric unit watt per square metre, but with the power at each wavelength w…
