Human eye is sensitive to wavelength in the range of

Options

(a) 300-900 nanometer
(b) 380-760 nanometer
(c) 790-800 nanometer
(d) 300-360 nanometer

Correct Answer:

380-760 nanometer

Explanation:

400 to 700 nm range of wavelength are “visible” because these are the wavelengths to which our eyes are sensitive. The cone cells of the human eye are sensitive to 3 wavelength ranges which the eye interprets as blue (narrow, with a peak near 419nm), green (broader, with a peak near 531 nm) and red (also broad, with a peak near 558nm, which is actually more like yellow).
