Question

What is responsible for the production of x ray emission at the cutoff wavelength?

Answer 1

Answer:

correct answer is option 5 (The emission by the incident electron when it loses its energy in a single emission)

Explanation:

The emission by the incident electron when it loses its energy in a single emission then X-rays of minimum wavelength which is also known as X-rays of cut-off wavelength are emitted.

If potential V is applied on coolidge tube then cut-off wavelength of the continuous X-ray spectrum is related to the accelerating potential  V   by following equation

$\lambda_{cut-off} =\frac{hc}{eV} =\frac{12400}{V}$ Angstrom/V
