Physics

The Physics Classroom: Free website with great resources: http://www.physicsclassroom.com/

Nuts about Geometry - http://library.thinkquest.org/J002441F/

Physics takes math formulas and applies them to our real world.

OK - Here are some basic web sites that explain Physics - so you can look up terms & formulas

Easy Calculation - helps you understand terms, formulas, and you can verify some math.

Here is their Math-dictionary http://easycalculation.com/maths-dictionary/

Wiens Law from their Math-dictionary http://easycalculation.com/maths-dictionary/wiens_displacement_law.html

And Wikipedia http://www.wikipedia.or.ke/index.php/Wien's_displacement_law

You can see the definition, the formula, and a sample of what the graph would look like.

λ = b / T

λ=wavelength

T = absolute temperature of the black body

A black body is considered the perfect absorber and emitter of energy

everything it absorbs will emit back with no energy lost.

b is Wien's displacement constant. b = .0029KM (2.8977685 x 10^-3 meter-Kelvin)

T = λ / b

b = λ * T

Astronomy On Line is a good resource: http://aoblog.org select Science and look on the left navigation for topics - Wiens Law is all the way at the bottom.
