11 Mar 2009, 2:55 PM  |  Electromagnetic Spectrum Detection You can hide this advertisement by registering. hey any help would be appreciated....i gotta "Identify the limited range of wavelengths of the electromagnetic spectrum detected by humans and compare this range with those of other vertebrates and invertebrates." any suggestions. (tables preferred but i will take any help i can get!) Cheers... Ernie. ************************************************** ****************** HE WHO LAUGHS LAST THINKS THE SLOWEST |

20 Nov 2009, 12:19 AM   | Re: Electromagnetic Spectrum Detection identify the limited range of wavelengths of the electromagnetic spectrum detected by humans and compare this range with those of other vertebrates and invertebrates * The electromagnetic spectrum consists of waves of varying wavelengths. These waves include visible light, infra-red radiation and ultraviolet radiation. Blue-green light (500 nm) is the most effective wavelengths for humans. Either side of this wavelength in the red and ultraviolet areas are less effective in humans but are used by other organisms. * A table like the one below is an effective tool to assist you to organise information. Type of animal Name of animal Part of electromagnetic spectrum detected Wavelengths detected Vertebrate Human visible 700-400 nm Rattlesnake infra-red and visible 850-480 nm Japanese dace fish ultraviolet and visible as low as 360 nm Invertebrate Honeybee ultraviolet and visible 700-300 nm Mantis shrimp ultraviolet and visible 640-400 nm |

16 Jul 2009, 10:43 PM | Re: Electromagnetic Spectrum Detection 400>380. Why isn't that human can detect UV. A as well?

400 is > 380, and humans see from 400-700, which is the visible spectrum... | |

16 Jul 2009, 10:43 PM | Re: Electromagnetic Spectrum Detection Sorry. What I mean is that human can detect visible light, eh? And it's stated to be from 380 to 750. Anything under 380 and down to 1nm is of UV. According to yours, UV is up to 400. And according to Con. Chem, UV. A has the wavelength from 320 to 400. Um, I'm just wondering who is correct here?

Visible light doesn't automatically become UV at 379 nm, so technically they're both right. | |
