How long does it take to emit an electron from an atom?

Einstein’s photoelectric effect: The time it takes for an electron to be released.

The image shows that different vocalization-related neural signals occurring across frontal cortex laminae (left) precede the two types of sounds (right) uttered by bats (species: Carollia perspicillata). The sounds are shown as color-coded time-frequency representations. One example social call is shown in the top right and one example echolocation call in the bottom right. Copyright: Julio C.
