The spectrum of white light lies:
Correct answer: C. In between UV and IR
- A. Above 300 nm
- B. Below 300 nm
- C. In between UV and IR
- D. None of these
Explanation
Option C is correct since white light is visible light (between IR and UV), and it contains all the colors of the rainbow, from red to violet. The range of visible wavelengths is 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.
