All of the following are properties of X-rays EXCEPT that they

Correct answer: C. Are deflected by electric and magnetic fields.

  • A. Are diffracted by a crystal lattice.
  • B. Pass through wood and flesh easily.
  • C. Are deflected by electric and magnetic fields.
  • D. Travel in a straight line with the velocity of light.

Explanation

The correct answer is that X-rays are not deflected by electric and magnetic fields. This is because X-rays are a type of electromagnetic radiation, which means they are uncharged and not susceptible to deflection by such fields. This distinguishes them from charged particles, which can indeed be influenced by magnetic and electric fields.Option A is incorrect because X-rays can indeed be diffracted by a crystal lattice due to their wavelength being similar in scale to the atomic spacing in crystals. Option B is incorrect because X-rays are known for their ability to penetrate materials like wood and flesh, which makes them useful for medical imaging. Option D is incorrect because X-rays, like all electromagnetic radiation, travel in straight lines at the speed of light when in a vacuum or a uniform medium.

About Atomic Spectra

Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
