Question

In the continuous part of the spectrum of X-rays, the limiting frequency is

• A. inversely proportional to the potential through which electrons have been accelerated
• B. directly proportional to the accelerating potential
• C. not dependent upon the acclerating potential
• D. is dependent upon the nature of the target material

Answer 1

The correct option is B directly proportional to the accelerating potential

The maximum frequency is given by ${\nu }_{max}=\frac{eV}{h}\Rightarrow {\nu }_{max}\propto V$
Hence, the correct choice is (b).
