Please explain:
Complementarity: any given application of classical concepts
precludes the simultaneous use of other classical concepts which in a
different connection are equally necessary for the elucidation of the
phenomena. Bohr 1934),

please explain me compton effect and its importance.....?

Why the Probability Distribution Function is always Positive?

Explain Why p-orbitals are often presented as Px, Py, Pz instead of Po, P+1, P-1 ?

A broadcasting power of 300kw, if the energy of each photon emitted is 0.000000414ev.calculate the broadcasting frequency and the total number of photon emitted.

why we say that there is uncertainity in measuring the position and momentum of electron simultaneously according to heisenbergs uncertainity principle although we say that momentum of electron is fixed at every position according to formula mvr=nh/2pi ..so if we measure the position accurate than at that point its momentum should be fixed

Hi I am in 12th grade and have a couple questions. obviously they are based on simplified views of physics because of my level of learning but I frequently look up physics lectures so i am not completely ignorent. I have also looked up online for this answer but it is elusive.

I am currently in a calculus section involving higher orders. f(x)=cosx is a representation of a light particle's wave length is it not? so are sinx, -cosx and -cosx. all different views. however these repeat themselves over and over again when made to higher orders and i would assume it would do the same with integrals. is this why light cannot accelerate in a mathematical view? because it physically cannot do anything else but have the same "speed, acceleration, jerk etc...". I put quotations because they all, in this case, do the same thing in space and time.

If I am entirely wrong or on my best hopes even partially wrong. please give a detailed feedback.

Thank you
