Q1: The sensitivity of human eyes is maximum atA white portion of spectrum
B green portion of spectrum
C red portion of spectrum
D violet portion of spectrum
ANS:B - green portion of spectrum The sensitivity of the human eye to light of a certain intensity varies strongly over the wavelength range between 380 and 800 nm. Under daylight conditions, the average normal sighted human eye is most sensitive at a wavelength of 555 nm, resulting in the fact that green light at this wavelength produces the impression of highest "brightness" when compared to light at other wavelengths. |
