Among the following particles, which will have the shortest wavelength when accelerated by one million eV?

Answer»

Neutron
Tritium atom
`alpha`- PARTICLE
Electron

Solution :Wavelength is INVERSELY proportional to the MASS of teh particle `lamda=h/(MV)`
Since `alpha` particles have the largest mass (4 a.m.u. ), these will have SHORTEST wavelength.
