Question

What is the range of frequencies are our eyes sensitive to?

Answer 1

400-800 nanometer which is the visible light

Answer 2

Answer:

The wavelength of this visible light ranges of our eye from '700 nanometers' down to '400 nanometers'.

Explanation:

• Our 'eyes are sensitive' only to small portion or a narrow band of frequencies collectively termed as electromagnetic spectrum.
• The visible range of light receives sun’s radiation. Each wavelength in the visible spectrum refers to a particular colour, with red having the 'longest wavelength' and violet having the shortest wavelength.
• The human eyes have maximum sensitivity in the wavelength of about 555 nm which matches the green colour in the visible spectrum.
• White color is perceived when all the colors or wavelengths of the visible spectrum meet the 'eye at the same time'.
