Heisenberg's uncertainty principle states that we cannot simultaneously measure both the position and momentum of an object better than a certain accuracy. this limitation is not a consequence of imperfect technology, but is a fundamental law. it applies to all objects -- photons, electrons, baseballs, etc.. a highly monochromatic, continuous beam of laser light of wavelength 470 nm passes through an electro-optic shutter. the shutter opens and closes in a time interval of δt = 90 ps . after passing through the shutter to what uncertainty, δx, have the photons been localized?

What are chlorofluorocarbons and what impact do they have on the atmosphere?

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.

Give an example in which the electrical energy changes to light energy
