In CAT, the beam of X-rays used is of
Correct answer: C. fan-shaped
- A. spherical-shaped
- B. pencil-shaped
- C. fan-shaped
- D. circular-shaped
Explanation
C is the right option In computed tomography (CAT or CT), the X-ray beam used is typically fan-shaped. This type of beam allows for the acquisition of cross-sectional images of the body.

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.
