Debroglie Wavelength

If a ball A of mass m_A = m/2 moving along x-axis collides elastically with ball B of mass m_B = m/3 initially at rest and they move along x-axis. If initially velocity of ball A was v_0 . And initially de-broglie wavelength of ball A is lambda_0 . Find change in debroglie wavelength delta lambda of ball A in terms of lambda_0

A particle X moving with a certain velocity has a debroglie wave length of 1A^(@) . If particle Y has a mass of 25% that of X and velocity 75% that of X, debroglies wave length of Y will be :-

In sample of hydrogen atoms in ground state, electron make transition from ground state to particular excited state, where path length is four times of debroglie wavelenght . Electrons make back transition to the ground state prouducing all possible photons. Debroglie wavelenght of electron which is emitted from the fianl excited dtate of above hydrogen sample, when photon of 1eV collide with it

The de-broglie wavelength of neutron at 27^(@)C is lambda . The wavelength at 927^(@)C will be

The de-broglie wavelength of a photon of an electromagnetic radiation is..........the wavelength of the radiation.

When photons of energy 4.25eV strike the surface of a metal A, the ejected photoelectrons have maximum kinetic energy, T_A (expressed in eV) and deBroglie wavelength lambda_A . The maximum kinetic energy of photoelectrons liberated from another metal B by photons of energy 4.20V is T_B = T_A -1.50eV . If the deBroglie wavelength of those photoelectrons is lambda_B = 2lambda_A then

The wavelength of light from the spectral emission line of sodium is 589nm. Find the kinetic energy at which (a) an electron and (b) a neutron would have the same deBroglie wavelength. Given that mass of neutron =1.66xx10^(-27)kg

An electron is confined to a tube of length L. The electron’s potential energy in one half of the tube is zero, while the potential energy in the other half is 10eV. If the electron has a total energy E = 15 eV , then the ratio of the deBroglie wavelength of the electron in the 10eV region of the tube to that in the other half is -

A particle X moving with a certain velocity has a debragile wave length of 1.72Å , If particle Y has a mass of 50% that of X and velocity 50% that of X , debroglies wave length of Y will be -
