The potential through which an electron should be accelerated, so that, on collision it can lift the electron in the atom from its ground state to some higher state is known as:
Correct answer: B. Excitation potential
- A. Ionization potential
- B. Excitation potential
- C. String potential
- D. Acceleration potential
Explanation
Excitation potential refers to the minimum energy required to excite an atom or molecule from its ground state to a higher energy state, typically an excited state. This concept is crucial in fields like atomic physics, quantum mechanics, and spectroscopy.

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.
