during the plank constant experiment when we determine current using photo detactor we get maximum current int infra red region.

That just means the detector was most sensitive to infrared light.  It just depends on what material the detector was made of.

I've never experienced a phenomenon that could not be related to some outside perturbation\n\nAs for the human retina, it has about 125 million rod photoreceptor cells (plus about 6 million cone cells, used mostly at night).  On a surface roughly 1/4th of that of a full format digital SLR today, the retina has about 10x more "pixels", i.e. a density 40x higher (and our own "pixels" don't interfere w eachother, unlike those of cameras ;-)\n\nGiven that from even as low as 10 megapixels is is pretty much impossible to see any on a postcard size print, I'd be very surprised if anyone could identify individual megapixels in the case of our own 125 megapixel camera ;-)\n\nhope this helps\n\na

It probably requires a mass spec technique.  Infrared might work.  Your detection level will be the problem.

i think you are correct on that.the only problem is that the substances of this byproduct could effect the particle generator with the obvious results on the galactic balance.

use E=(hc)/lambda\nwhere h is plank's constant 6.63e-34\nc is the speed of light 2.99e17 nm\nE is energy\n\nlambda is the resulting wavelength.

easy. u need to bias the LDR and have a ammeter to monitor the current. to  detect a wavelength u need to have a monochromator because the LDR will detect everything within its wavelength dependent range.

It appears that the constants are calculated at one condition (dry,wet,etc) whereas the effective is closer to reality.  See\n\nhttp://www.pnas.org/cgi/content/full/102/45/16293

The PD will decrease as the current passing through it will drop due to current division

i would try to find two sheets of a fine metal mesh. Use the first sheet to charge the incoming air and the second sheet as the negative attracting grid. place them about an inch from eachothers and attach the positive and negative terminals each to a sheet. I would use a car battery as this gives you the most voltage of something that is portable. Whatever source you get make sure it is dc and that each sheet of wire mesh is insulated from the other or else the electrostatic effect wont work. Or if you have ever seen the ionic breeze by sharper image it uses three or four metal plates placed side by side to achieve dust collection. This may work also.

Yes. those of frequency higher than infra red are absorbed by the PV. IR travels right through the silicon in the PV
