What happens to the frequency of x-rays as their energy increases?

As the energy of x-rays increases, their frequency also increases. This relationship is described by the equation ( E = h \cdot f ), where ( E ) is energy, ( h ) is Planck’s constant, and ( f ) is the frequency of the electromagnetic radiation. When energy increases, because Planck's constant remains constant, the frequency must also increase to satisfy the equation.

In the electromagnetic spectrum, x-rays are part of the higher energy range, above ultraviolet and below gamma rays. Higher energy x-rays, used in medical imaging, have shorter wavelengths and correspond to higher frequencies. This fundamental principle underlies many applications in radiography and radiation therapy, impacting image quality and dose management in clinical settings.

Choosing this option reflects an understanding of the direct relationship between energy and frequency in the context of electromagnetic radiation, pivotal for understanding x-ray production and interaction with matter in medical imaging.
