Graph shows relation between intensity (I),wavelength for X-rays emitted from collidge tube if minimum wavelength is lambda_(mu) and wavelength of K_(prop) line is lambda_(K).By increasing accelerating voltage

Answer»

`lambda_(K)-lambda_(mu)` increase
`lambda_(K)-lambda_(mu)` decrease
`lambda_(K)` increase
`lambda_(K)` decrease

Solution :In `lambda_(mu)=(hc)/(E )=(hc)/(EV)`,h,c and e are constant
`therefore lambda_(mu)PROP (1)/(V)`
Now INCREASING V,`lambda_(mu)` will decrease HENCE distance between `lambda_(K)` and `lambda_(mu)` will increases.
