What is the wavelength associated with an electron moving with a velocity of 106 m/s ?
aadhi111:
it is easy:wavelength = planck's constant / mass x velocity
i will solve it 6.626 x 10^-34/9.1 x 10^-31 x 106
the answer is 0.00000686916 = 6.86916 x 10^-6
i take h = 6.63*10^-34 so this is difference in answer .but the value is so small its do not any matter .if value is small just see order of magnitude and before decimal integer and after decimal first integer.

lambda = h/p
= h/(m*v)
=6.63*10^-34 / (9.1*10^-31*106)
= 6.873*10^-6 m.
= h/(m*v)
=6.63*10^-34 / (9.1*10^-31*106)
= 6.873*10^-6 m.

there is no connection between wavelength and electron.
seshan we hav connection with the mass of electron with wave length
