The Visible Spectrum for Humans Extends Between a Wavelength Of

Question

The visible spectrum for humans extends between a wavelength of
A) 700 and 1000 nm.
B) 100 and 200 nm.
C) 200 and 400 nm.
D) 2000 and 2500 nm.
E) 400 and 700 nm.

Accepted Answer

The visible spectrum for humans extends between wavelengths of 400 and 700 nm. This range includes the colors of the rainbow, from violet (400 nm) to red (700 nm). Option A is incorrect because it extends beyond the visible spectrum to infrared wavelengths, and option B is incorrect because it extends to ultraviolet wavelengths. Option C is also incorrect because it does not encompass the full visible spectrum, and option D is incorrect because it includes wavelengths that are not within the visible spectrum for humans.
