Ma uitam acum peste niste modele generate cu Mathematica 7.
Am dat peste ceea ce cauti tu, intr-adevar, e interesant experimentul. Poate o sa-l fac in realitate.
Cica se poate calcula prin Velocity = Frequency x Wavelength.
Practic autorul modelului spune ca poti pune o tava cu "chocolate chips" sau orice material care se topeste usor la microunde, si sa masori distanta dintre punctele de topire. Ar trebui sa fie in jur de 6 cm.
Uite aici tot textul in engleza.

"Place a plate with a single layer of marshmallows in a turntable-free microwave, and zap it until some of them just begin to melt. Measure the distance in centimeters between melt spots; it should be roughly 6 cm. Next, find a sign with the frequency of the microwave, usually 2450 MHz. With these two pieces of data, the speed of light can be calculated, via Velocity = Frequency × Wavelength. Chocolate chips or another substance which melts nicely may be substituted."

Daca te interesaza modelul, trebe sa downloadezi Mathematica Player, care e gratuit si din linkul urmator iti iei modelul. Eu m-am jucat cu el, si e interesant :)
