Hello, I was wondering if someone could explain to me what does it meant that a beta particle has a range of energies ? Thanks

I'm going through a textbook, on what is pretty much my first course in Quantum mechanics. I've got to a section were it says that in order for a sinusoidal wave function to correspond to a non infinite probability distribution, there must be a range of momentum, or at least more than 1 momentum...

6) REDUCTION OF DURATION? Why are the durations of species of hominids decreasing over time? The more modern the hominid, the shorter its existence. For example, according to wikipedia, Homo erectus lived from 1,900,000 BC to 70,000 BC. By comparison, the more recent neaderthals lived...

Good day everyone. I would like to know about the lower limit of the frequency range of active acoustic phonon modes. Textbooks say it can reach zero. But I am curious about whether it can be very small, such as 1 micro volt or the like. Would a phonon mode of so small energy be of any...

The weak value of an observable A with pre-selected state ##\psi## and post-selected state ##\phi## is defined as: A_w =\langle \phi | A | \psi \rangle / \langle \phi | \psi \rangle References like Wikipedia then include a comment that the weak value is not bounded by the range of eigenvalues...

I see the term o"ptical frequency" in some articles. From Wikipedia I read that it means the whole EM spectrum. But something says to me it may be only the visible part of the spectrum. Now, which definition is correct? Thanks

Recently it struck me that I'm not sure I understand the weak interaction at all. What causes it to happen? I know that its mediated by the W and Z bosons and has a short range as a result of the large mass these bosons posses, but what does that range refer to? Range from what?!

I'm interested in applying inertial navigation over a very small range < 2 meters. Everything I have seen so far that is related to using inertial navigation for dead reckoning is for very large scales and gives accuracy on the order of fractions of miles or several feet. Does anyone know what...

State the range of the reciprocal function of f(x) = - (x+3)^2 - 1. I'm not sure if I did this right. I wrote that y is above/equal to -1 and below/equal to 0. Is this correct? Also, how would you graph the reciprocal function of f(x) if there is no VA and only a HA?
