How to calculate the number of spectral lines emitted or absorbed ?
a proper defination of "distance of closest approach."
A 12.5 eV electron beam is used to bombard gaseous hydrogen at room temperature. What series of wavelengths will be emitted?
In Rutherford experiment the number of alpha-particle scattered through an angle of 60 is 112 per minute,the find the number of alpha particle scattered through an angle of 90 per minute by the same nucleus.
1. why alkali metals are most suitable as photosensitive surfaces?
2. can we get photoemission with an intense beam of radiowaves?
3. is photoelectric emission at all frequencies?
4. what is minimum angular momentum of electron in hydrogen atom?
5. which quantity of the orbiting electron has same dimension as that of h?
6. how many spectral lines are possible in hydrogen spectrum?
7. which hydrogen spectral series is found first?
8. which parameter is same for all photons in laser tube?
9. which microscope will you use to study surface structure of different materials?
why ZnS screen was used by rutherford?
plz calculate the ratio of energies of photons produced due to transition of electron of hydrogen atom from its a)second permitted energy level to the first level b) highest permitted energy level to the second permitted level.
what is the significance of negative energy of electrons in the orbit?
The total energy of an electron in the first excited state of the hydrogen atom is about −3.4 eV.
(a) What is the kinetic energy of the electron in this state?
(b) What is the potential energy of the electron in this state?
(c) Which of the answers above would change if the choice of the zero of potential energy is changed?
find distance of closest approach when 5Mev proton approaches a gold nucleus(Z=79)?
the answer is 2.3X10^-14.........but im not able to get this answer
For a certain atom,there are energy levels A,B,C corresponds to energy values EA<EB<EC.Ifλ1,λ2,λ3 are the wavelengths of radiations corresponding to transisition from C to B,B to A, and C to A respectively.Then find a relation betweenλ1,λ2,λ3.
