Which of the following regarding X Rays is INCORRECT:
Correct answer: A. Have higher wavelength than visible light
- A. Have higher wavelength than visible light
- B. They are part of electromagnetic spectrum
- C. They are highly penetrating in soft body tissues
- D. They are high energy photons
Explanation
This statement is incorrect. X-rays have a shorter wavelength than visible light, typically in the range of 0.01 to 10 nanometers, while visible light wavelengths range from about 400 to 700 nanometers.

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.
