A potential difference of 30KV is applied across an X-ray tube. Find the minimum wavelength of X-ray generated.

`7.07xx10^(-2)A`

`4.133xx10^(-10) m `

`7.07 xx10^(-10)m`

`4.133 xx10^(-11) m `

Text Solution

Verified by Experts

The correct Answer is:

`lambda=1240/30000=41.3 xx10^(-3) nm`
`=41.3xx10^(-12) m`
`=4.133xx10^(11) m `
