The human visual system responds within very narrow range of the electromagnetic range: from about _______ nanometers.
A) 1 to 100
B) 100 to 200
C) 400 to 700
D) 1,000 to 10,000

Question

Quizplus · Accepted Answer

The human visual system responds within a narrow range of the electromagnetic spectrum, specifically from wavelengths of about 400 to 700 nanometers. This range is known as the visible spectrum and includes the colors we can perceive with our eyes. Option A, 1 to 100 nanometers, is incorrect because this range falls within the ultraviolet spectrum, which is not visible to humans. Option B, 100 to 200 nanometers, is also incorrect because this range is within the vacuum ultraviolet spectrum, which is not visible to the human eye. Option D, 1,000 to 10,000 nanometers, is incorrect because this range falls within the infrared part of the spectrum, which is also not visible to the human eye.
