Final answer:
The burst of light released when an electron jumps between shells is called the photoelectric effect. The frequency of the light released is proportional to the energy jump.
Step-by-step explanation:
The burst of light that is released when an electron jumps from an outer shell to an inner shell or from high energy to low energy is known as the photoelectric effect. It is a phenomenon that occurs when light shone onto a metal surface causes the ejection of electrons from that metal. The frequency of the light released is proportional to the energy jump between the shells or energy of the incoming light.
