which of following has largest de-broglie wavelength of same speed?A.eletronB.protonC.alpha particleD.none of these

ELECTRON WILL HAVE HIGHEST DE-BROGLIE WAVE LENGTH

PLS APPROVE IT

electron willhave highesr de-broglie wavelength

pls approve

electron

de-broglie wavelength = h/mv

here h is placks constant and v is same speed considered for all.

It means particle which has larger mass will have les wavelength.

Now U can calculate!

Plz approve!

Approved

Option A

c

electron will have highest de-broglie wavelength

                                                                               plsss approve

 de-broglie wavelength =  h/mv

as speeds are same and h is planck''s constant so

   finally wavelength is only inversely proportional to their masses..

and as electon has smallest mass of all three so de broglie wavelength for elrctron is largest.

i.e opt (a)_ is correct..
