Answer #1

V     = 2.2*10^6 m/sec

m   = 9.1*10^-31Kg

h    = 6.625*10^-34 joule-sec

    = h/mv

      = 6.625*10^-34/9.1*10^-31*2.2*10^6    = 3.3*10^-10m >>>>>answer

        = h/mv

the relationship between wavelength of a particle and its velocity inversly proportinal. >>>>anser

    = 3.3*10^-10m     U.v region >>>>answer
