In a solid-state detector, the p-n junction is operated under
Correct answer: B. reverse bias
- A. forward bias
- B. reverse bias
- C. no bias at all
- D. reverse bias for small energy particles and no bias for large
Explanation
B is the right option In a solid-state detector, the p-n junction is typically operated under reverse bias conditions. This allows for the efficient collection of charge carriers generated by incident radiation, improving the detector's sensitivity and response.

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.
