human eyes, therefore, occupies only a very narrow band in the whole 【M4】______
electromagnetic spectrum. Ultraviolet rays are invisible to humans though
ants and honeybees are insensitive to them. Humans have no direct perception 【M5】______
of infrared rays like the rattlesnake that has receptors tuned into 【M6】______
wavelengths longer than 0. 7 micron. The world would look eery different 【M7】______
if human eyes are sensitive to infrared radiation. Then instead of the darkness 【M8】______
of night, we would be able to move easily in a strange shadowless world
where objects glowed with varying degrees of intensity. But human eyes excel
in other way. They are in fact remarkably discerning in color gradation. 【M9】______
The color sensitivity of normal human vision is rarely surpassed even 【M10】______
sophisticated technical devices.
