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

1)the last emission in a series of many emissions by the incident electron as it loses its energy.

2)the first emission in a series of many emissions by the incident electron as it loses its energy.

3)the most energetic emission in a series of many emissions by the incident electron as it loses its energy.

4)the least energetic emission in a series of many emissions by the incident electron as it loses its energy.

5)the emission by the incident electron when it loses its energy in a single emission

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

Angstrom/V
