Question

What does the absorption spectrum of an atom show?OA. The amount of energy that is absorbed as the element changesphaseB. The temperature of the phase transitions of the element atdifferent pressuresC. The wavelengths of light that an atom gives off when electrons falback to lower energy levelsOD. The wavelengths of light that cause the electrons in the atom tomove to higher energy levels

Answer 1

The absorption spectrum of an atom is widely used to determine specific elements in different places, like different planets for example, and as the name suggests, this spectrum is the opposite of the emission spectrum and it is related to the absorption of energy in form of light. Therefore the best explanation for absorption spectrum is the electron moving to a higher energy level, since it is absorbing energy. Letter D is the best option, since letter c
