Re: Wavelike Properties [ENDORSED]

Larger objects do have wavelengths, they are just negligible, since their masses are so large, when dividing by plank's constant you will see that there is a wavelength but that it is just too small to be even considered

Why is it that the hydrogen spectrum doesn't have equal differences between states (n=1 to n=2 is a lot bigger than the differences between any other energy levels)?

Re: Threshold Energy Definition

The threshold energy is the amount of energy required to move an electron from a certain metal. It is the "phi" symbol in the equation we use for determining the kinetic energy of an electron from last class.

Re: General Question about Joules [ENDORSED]

Hi! The reason that Joules can also refer to kg(v.s) is because that is the work equation and that is the energy expended moving a mass of a given amount at a certain velocity.
