Peak sensitivity wavelength
WebDec 1, 2024 · It can be found that the linearity between the peak wavelength and na is good. In order to obtain the average wavelength sensitivity, the linear fitting between the peak wavelength and na is given in Fig. 3c. The linear regression equation is obtained as λ ( μ m) = 11.35 0 n a - 15.113. WebExperiments by George Wald and others showed that rods are most sensitive to wavelengths of light around 498 nm (green-blue), and insensitive to wavelengths longer than about 640 nm (red).

Wien's displacement law is relevant to some everyday experiences: • A piece of metal heated by a blow torch first becomes "red hot" as the very longest visible wavelengths appear red, then becomes more orange-red as the temperature is increased, and at very high temperatures would be described as "white hot" as shorter and shorter wavelengths come to predominate the black …
