Electronic emission involves electrons transitioning between energy levels in response to energy inputs, primarily from light. When light hits an electron, it can gain energy and move to a higher energy level. Conversely, when it drops to a lower energy level, light is emitted. ;
Electronic emission involves electrons transitioning between energy levels due to energy changes. When light is absorbed, an electron can jump from a lower to a higher energy level. Conversely, when an electron drops to a lower level, it emits light, confirming that option B is correct.
