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

Options

A. `lambda_(K)-lambda_(mu)` increase
B. `lambda_(K)-lambda_(mu)` decrease
C. `lambda_(K)` increase
D. `lambda_(K)` decrease

Answer

A

Explanation

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.
