Hi there, so for this problem, we're told that in quantum mechanics, the fundamental constant called plants constant that we call h has dimensions of, so that is constant, has dimensions of meters, sorry, mass, length square, times time to the minus one.
00:32
So those are the dimensions for plam's constant.
00:39
And we need to construct a quantity with the dimensions of length from plumstant, a mass, and the speed of light.
00:54
So the mass, the dimensions of mass are just mass, and the dimensions of mass, and the dimensions of the speed of light.
01:11
Are just length times times to the minus 1.
01:21
So what we need to do is to make a product between these three quantities in a convenient way such that we obtain units of length.
01:36
So what we can try to do is to divide plans constant...
