1.	If the velocity of the electron is 1.6xx10^(6) "ms"^(-1) , calculate the de-Broglie wavelength associated with this electron .
Answer» `3.2xx10^(-7)` m `2xx10^(-7)` m `4XX10^(-7) m` `0.5xx10^(-8)` m Solution :`lambda_A = (h_A)/(P_A) ""lambda_B = (h_B)/(P_B) "" P_B = 1/4 P_A` , `(8 xx 10^(-7))/(lambda_B) = 1/4 implieslambda_B = 32 xx 10^(-7) m `
