Which one of the following is not a property of the X-rays?

Result
Your answer: —  Â·  Correct: A
Explanation

X-rays are a form of electromagnetic radiation, similar to visible light and gamma rays, but with much shorter wavelengths, typically ranging from 0.01 nm to 10 nm [3]. Because X-ray photons carry no electrical charge and have no rest mass, they are not deflected by electric or magnetic fields [4]. This distinguishes them from charged particles like alpha or beta rays, which can be steered by such fields [4]. X-rays possess high energy, which is inversely proportional to their wavelength, granting them significant penetrating power through matter [2]. This penetration depth depends on the radiation's wavelength and the density of the material [2]. Therefore, the statement that X-rays are deflected by electric fields is incorrect, as they are charge-neutral photons that travel in straight lines [4].
