In an `x` ray, if the accelerating potential different is changed , then:

Options

A. The frequency of characterictic `x`-rays of a material will get changed
B. number of electrons emitted will change
C. the difference between` lambda_(0)` (minimum wavelength ) and `lambda _(kalpha)` (wavelength of `K_(alpha) `x` ray) will get changed
D. difference between `lambda_(k alpha)` and `lambda_(k beta)` will get changed .

Answer

C

Explanation

As the accelerating proportional difference is changed only the minimum wavelength changes. It has no effect on wavelengths of characteristic x-ray(whether they are produced or not ).
