Homework Statement Show that following statement is true: If Σa_n diverges, then Σ|a_n| diverges as well. Homework Equations Comparison Test: If 0 ≤ a_n ≤ b_n for all n ≥ 1, and if Σa_n diverges, then Σb_n diverges as well. The Attempt at a Solution I tried to prove the...

Hello. I have a conceptual question about Schrödinger Equation. In the textbook, it says that "Schrödinger Equation contains all the dynamical information that can be known about the wave function", but what exactly is "all dynamical information about the wave function"? Thanks in advance.

>atyy The example of sound helped a lot! Thank you!

Hello. I am reading about the wave packet in my physics textbook, and I understood that it describes the probability of a particle having a given position and a momentum in a particular state. However, I just cannot understand where those waves that consist the wave packet come from. I will...

>ZapperZ, atyy I see. So if the light intensity is high enough, an electron can obtain enough energy from multiple photons with energy lower than work function before the energy decays. It is very clear now, thank you so much!

Actually, would you mind explaining to me why "billions of slightly lower enegergy put together" cannot cause electrons to leave matter?

I see. So only the thing they could explained with classical physics was that light could knock out electrons out of matter under some circumstances. Thank you very much for the very concise answer! I see, so without photon theory explanation is very tough. Thank you!

Hello. I have a question regarding photoelectric effect. My textbook says that when photoelectric effect experiment was first performed, physicists could not explain the outcome with classical physics (e.g. maximum kinetic energy depends on frequency of light, not intensity). My question is...
