Kinetic energy of anti cathod material for which Z=41 is given by;                E1=hcλ=KZe22r12or             hcλ = -13
6Z12or               λ=-hc13
6×41=-6 6×10-34×3×10813 6×41=19
8×10-2613
6×41or               λ = 1
4641×10-26m=3 55×10-28m

atomic no. of anti cathode material is 41 in an x ray tube. wavelength of k alpha x ray produced in the tube is
