|Ejs Open source java applet Blackbody Radiation Spectrum Model for nm remixed by lookang from Fu-Kwun original and some codes adapted from lookang with some codes from Jose Ignacio Fernández Palop |
author: fu-kwun hwang lookang and Jose Ignacio Fernández Palop
|Ejs Open source java applet Blackbody Radiation Spectrum Model for nm earlier version|
a version exists in OSP http://www.compadre.org/osp/items/detail.cfm?ID=9387
Ejs Open source java applet Blackbody radiation curves customised for nm written by Fu-Kwun Hwang and customized by Loo Kang WEE
Ejs Open source Blackbody radiation curves customised for nanometre nm
This applet will show 5(with temperature text) to 10(in total) black curves of black body radiation curve between Tmin and Tmax.
Minimum temperature shown can be adjusted with left slider bar, Tmin=
Another curve in red is also shown (it's temperature can be adjusted with middle slider bar), T= Maximum temperature shown can be adjusted with right slider bar, Tmax= You can use it for study the intensity for black body radiation. If you want to study different temperature range, You can change Tmin and Tmax, to change the temperature range,too, currently it is set to 100 K to 10000 K. The x-axis shows the wavelength ⋏ is in nanometre for prefix 10-9 SI units
the intensity is in W.e-5 / (m2.nm)
The wavelength unit in the simulation is nm (nanometre), remixed from
