Question

The X-ray beam coming from an X-ray tube -

• A. is monochromatic.
• B. has all wavelengths smaller than a certain maximum wavelength.
• C. has all wavelengths greater than a certain maximum wavelength.
• D. has all wavelengths lying between a minimum and a maximum wavelength.

Answer 1

The correct option is D has all wavelengths lying between a minimum and a maximum wavelength.

X-rays are a type of radiation whose frequency (or wavelength) lie between a certain range of values.

Hence, option $\left(D\right)$ is the correct answer.
