differences in equation

Postby Madeline Lequang 1G » Tue Oct 23, 2018 12:42 pm

Why does the equation in the textbook say delta(p)delta(x)=h/2, but in the lecture notes, Dr. Lavelle uses h/4pi? Is there a difference? Which should I use?

I think in the textbook the h has a line through it. This is a different h value that equals h/(2pi). That's why the h/2 is still equal to h/(4pi). The equation is the same; the notation of the h just makes it appear different.
