numericals based on debroglie wavelength

Find the numerical value fo De Broglie wavelength of an electron in the 1^(st) orbit of hydrogen atom assuming Bohr's atomic model. You can use statndard values of the constants. Leave your answer in terms of pi .

If the velocity of the particle reduced to one third, then the percentage increase in its deBroglie wavelength is

Moving with the same velocity . One of the following has the longest deBroglie wavelength

Two particles of de-broglie wavelength lamda_(x) and lamda_(y) are moving in opposite direction. Find debroglie wavelength after perfectly inelastic collision:

Aphoton of energy 4.5 eV strikes on a metal surface of work function 3.0 eV. If uncertainty in position is (25)/(4pi)Å, find the uncertainty in measurment of deBroglie wavelength (inÅ ).

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 :-

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 :-

If the KE of free electron triples, its deBroglie wavelength changes by a factor

The graph between deBroglie wavelength (lamda) and (lamdap) is (p is the linear momentum of the particle)

The circumference of n^(th) orbit in H-atom can be expressed in terms of deBroglie wavelength lambda as :
