Based on the relative luminosity curve shown in the figure, determine the relative luminosity of wavelength 520 nm .

Step-by-step solution

The relative luminosity curve (photopic vision) represents the sensitivity of the human eye to different wavelengths of light under well-lit conditions. The peak sensitivity of the human eye occurs at a wavelength of 555 nm , where the relative luminosity is defined as 1.0 . As we move away from this peak, the sensitivity decreases. Based on the standard relative luminosity curve (which the given figure would represent), the approximate values for wavelengths in this range are: 500 nm 0.34 510 nm 0.52 520 nm 0.68 5
