Question

Patients in a doctor’s office are rightly concerned about receiving a chest X-ray. Yet visible light is also a form of electromagnetic radiation and they show little concern about sitting under the bright lights of the waiting room. Explain this discrepancy.

1. X-ray photons carry considerably more energy so they can harm the patients.
2. X-ray photons carry considerably less energy so they can harm the patients.
3. X-ray photons have considerably longer wavelengths so they cannot harm the patients.
4. X-ray photons have considerably lower frequencies so they can harm the patients.

Answer 1

shorter wavelength and high frequencies cause more damage to patients as high frequency carry more energy

so option a is correct

i.e. a . X-ray photons carry considerably more energy so they can harm the patients.
