Find the minimum wavelength of X-rays produced by 30 kV electrons.
Potential of the electrons, V = 30 kV = 3 × 104 V
Hence, energy of the electrons, E = 3 × 104 eV
e = Charge on an electron = 1.6 × 10−19 C
The minimum wavelength produced by the X-rays is given as:
`lambda = c/v`
`= (3xx10^8)/(7.24xx10^18) = 4.14 xx 10^(-11) m = 0.0414 nm`
Hence, the minimum wavelength of X-rays produced is 0.0414 nm.
