Question

Which of the following statements is/are correct for an x-ray tube ?

• A. On increasing potential difference between filament and target, photon flux of x-rays increases
• B. On increasing potential difference between filament and target, frequency of x-rays increases
• C. On increasing filament current, cutoff wavelength increases
• D. On increasing filament current intensity of x-rays increases

Answer 1

Answer: (B), (D)

On increasing potential difference between filament and target, frequency of x-rays increases
On increasing filament current intensity of x-rays increases

On increasing potential difference between filament and target, frequency of x-rays increases, On increasing filament current intensity of xrays increases
So, the answers are option (B) & (D).
