Hi all, i want to ask use of scintillator. Actually what i studied that to convert highly energetic gamma rays, to visible photon we use scintillator before p.m. tube, so that photoelectric effect can occur and we get photo-electrons. But when gamma rays interact with matter in three different...

Hi all,my question is on dynodes. For ex: in scintillation detector we ususally say that a visible photon when incident on photocathode,undergoes photoelectric effect.But what the process occurring on dynodes when this photoelectron incident on it. Electrons are multiplying successively as...

Hello everybody, actually yesterday i read about an experiment "ATTENUATION OF GAMMA RAYS". can anybody tell me what is meanning of word ATTENUATION.And why we are measuring it? i.e. what is the sigificance of measuring it?

Hi everyone, Can anybody solve my simple problems of quantum: Usually we say, that wave function Ψ is dependent on r,θ,Φ .But this is just a coordinate system,or more than that. Imagination to this is qite difficult. Moreover somewhere in a book I have read that if Ψ = f(r,θ) exp(imΦ),then on...

Gravitation Well gentleman i am not too great in physics and i believe that DH has given the best possible answer, i would like to add some thing to this.Actually answer to second response is itself hidden in your question. You are saying when matter particles come closer,they become...

Sorry genleman i can't understand what's that FAQ

eigen value problem Dear friend i don't know much of physics,but to me,its called eigen value equation bcoz we can write it in simple form as H(psi) = E(psi) H being hamiltonian or total energy of system,and E being energy eigen value.

One thing which is not clear to me in Bohr's model of hydrogen atom, that if accelerated charge radiates electromagnetic waves or radiations,then why in atom electron being a chrged particle retains its energy and rotates in specific orbits. with regards
