if de broglie wavelength of a baseball moving at a speed v=10m/s, and m=660 g is y(baseball) and for for a electron with k.e.=150 ev is denoted by y(baseball)

 If de Broglie wavelength of a baseball moving at a speed v=10m/s, and m=660 g is Y(baseball) And for for a electron with K.E.=150 eV is denoted by Y(baseball) ,then the ratio Y(electron)/ Y(baseball) is approximately equal to.. (h=6.63 x 10 ^-34 Js)(Read Y as Lambda
