Question

X-rays are produced in X-ray tube operating at a given accelerating voltage. The wavelength of the continuous X-rays has values from

• A. $0to\infty$
• B. ${\lambda }_{min}to\infty ,where{\lambda }_{max}>0$
• C. $0to{\lambda }_{max}where{\lambda }_{max}<\infty$
• D. ${\lambda }_{min}to{\lambda }_{max},where0<{\lambda }_{min}<{\lambda }_{max}<\infty$

Answer 1

The correct option is D ${\lambda }_{min}to{\lambda }_{max},where0<{\lambda }_{min}<{\lambda }_{max}<\infty$

Wavelengths will lie between a ${\lambda }_{min}$ and ${\lambda }_{max}$ beyond which it wont lie in the range of xrays.
Hence option D is correct.
