That statement is incorrect. While both X-rays and light are forms of electromagnetic radiation, they differ significantly in their wavelength and energy.

Here's the breakdown:

* X-rays have shorter wavelengths and higher energies than visible light. This allows them to penetrate matter more readily, which is why they are used in medical imaging and industrial applications.

* Light is a form of electromagnetic radiation that our eyes can detect, with longer wavelengths and lower energies than X-rays.

Therefore, a thin beam of light is not called an X-ray. While both are forms of electromagnetic radiation, their properties are distinct.
