what is a absorbance spectrum?

Postby pre_vet_gal » Wed Feb 23, 2005 5:19 pm

I was wondering if there is anyone that could define what exactly is a absorbance spectrum? Thanks!

It's basically a chart of the amount of light absorbed at each wavelength of light, I think. Check those websites to make sure ;).

What others said. It's basically a graph that plots wavelength (x-axis) with absorbance (or transmittance, which is its inverse, on the y-axis). You'll find a lot of these graphs are very useful in the plant world, since light is necessary for growth and development, as oppose to animals it isn't as applicable.

I'm not sure if you need to know this for your own purposes but basically any wavelength that is not absorbed in significant amounts is reflected and that's what we see (chlorophyll is green because it absorbs all light except green light).

Robotics, I wanted to know - how are you involved with robotics - I'm involved in the FIRST robotics team at my high school...

YOu built robots? like in robot wars?

No... It's not like battle bots... our robots can't destroy or even try to damage another robot.... but some friendly contact is o.k. :twisted:

Hi Darwin, I'm not actually involved with any robotics, I just happen to like the name so I stuck with it since :)
