for a particle in a box,(adsbygoogle = window.adsbygoogle || []).push({});

why is U a constant=0 in the box but infinite on the outside?

also why when you are calculating the probabilty, the range is from negative infinity to positive infinity? and then why do you have to change it to go from 0 to L?
