It is denoted by W0. (b) Impact parameter, b = [(Ze2) (cot θ/2)]/[(4πε0)E], (c) Distance of closest approach, r0 = 2Ze2/(4πε0)E. (a) The central part of the atom called nucleus, contains whole of positive charge and almost whole of the mass of atom. NET/JRF; GATE; IIT-JAM/IISc; JEST; TIFR; Other M.Sc. e/m of an electron (Thomson Method):- (a) e/m of a particle is called the specific charge of the particle. (d) Electrons are capable of changing the orbits. In accordance to Bohr’s postulate of atomic structure, the angular momentum of an electron is an integral multiple of h/2π. Photo electric effect:- Photo-electric effect is the phenomenon of emission of electrons from the surfaces of certain substances, mainly metals, when light of shorter wavelength is incident upon them. using askIItians. (b) Change in wavelength:- λ' – λ =λc (1-cos?). subject, Here, r is the radius of curvature, B is the strength of magnetic field, v is the velocity, e is the charge on cathode ray particle and m is  the mass, (b) Number of photons incident per second, n. is the rest mass of electron and c is the speed of light.

For a particular orbit (n= constant), orbital velocity of electron varies directly as the atomic number of the substance. Einstein’s equation of photoelectric effect:-, (b) ½ mvmax2 = hf – hf0 = h(f- f0) = h [c/λ – c/λ0], Threshold frequency (f0):- f0 = work function/h = W/h, Maximum kinetic energy of emitted photo electrons:-, Threshold wavelength:- λ0 = c/f0 = hc/hf0 = hc/W, Momentum of photon:- p = E/c = h/λ = hf/c, For particle at temperature T, λ = h/√3mKT   (E = 3/2 KT), The wavelength of electron accelerated by potential difference of V volts is:-, (a) Number of photons per sec per m2, np = Intensity/hf, (b) Number of photons incident per second, np = Power/hf, (c) Number of electrons emitted per second = (efficiency per surface)× (number of photons incident per second).
