Question

Question 21 of 22Which of the following shows the wavelength of light that an atom gives off when an electron falls to a lower energy level?A. Absorption spectrumB. Quantum spectrumC. Electromagnetic spectrumD. Emission spectrum

Answer 1

D. Emission Spectrum

Step-by-step explanation

When an electron in an atom falls from a higher level to a lower level, energy is decreased and a photon is emitted. Photons are the carriers of electromagnetic and are the form in which electromagnetic radiation is transmitted/emitted.

When an electron falls to a lower level in an atom, light from a wavelength belonging to the emission spectrum is emitted.

Therefore, the answer is option D.
