h with a line through it?

[marcus lin 1E]

So Dr. Lavelle was talking about how h/4pi is the same as h with that line through it/2pi, can someone explain the difference?

[Yiting_Gong_4L]

H-bar is equal to h/2pi.

[Aili Ye 4L]

As the person stated above, h-bar is the same thing as h/2, there is no difference.

[ryanhon2H]

h bar is h/2π. The difference is in the Heisenberg equation where it could be (Δp x Δx) = h/4π or (Δp x Δx) = 1/2(h bar). 1/2(h bar) simplifies to h/4π

[Luc Lorain 1L]

It just represents another one of those symbols that physicists created to make their lives easier while writing calculations. Its a similar concept to the Hamiltonian, which represents a long expression related to wave-particle duality with the letter H.

h bar is h/2pi

[Sheridan Slaterbeck 1J]

H bar is just a short hand notation, that is used just to simplify what is written. ( Hbar= h/2 pi) (H bar/2 = h/4 pi)

[Jackie Ngo 1C]

h bar is essentially another way to say h/2pi. it can also be called Planck's constant, in case you didn't already know (I just discovered this in my discussion section)

[Jake Gordon 1A]

h bar is equivalent to h/2pi so...hbar/2 is equivalent to h over 4pi which is what the right side of the Heisenberg equation requires.
