The voltage applied across the cathode and anode of an X-ray generating machine is 50000V. Determine the shortest wavelength of the X-ray emitted. Given `h=6.62xx10^(-34)J*s`.

Text Solution

Verified by Experts

`eV=hnu_(max)=(hc)/(lambda_(min))`
[`nu_(max) and lambda_(min)` are respectively maximum frequency and minimum wavelength of X-ray photon]
`therefore lambda_(min) =(hc)/(eV)=((6.62xx10^(-34))xx(3xx10^(8)))/((1.6xx10^(-19))xx50000)=2.48xx10^(-11)m=0.248 "Å`
