Quantum superposition isn’t merely a theoretical curiosity; it underpins the functioning of technologies like quantum computing and quantum cryptography. These revolutionary fields harness the power of superposition to perform computations at speeds far surpassing classical computers and ensure secure communication channels resistant to eavesdropping.
If an electron absorbs a wave of high frequency (and thus energy), sometimes this energy is sufficient for the electron to abandon the atom entirely. This phenomenon, when electrons are released from the shell of an atom, is called the photoelectric effect. Electrons that are released in this manner are called photoelectrons.
Young’s experiment, often referred to as the double-slit experiment, is a relatively simple experiment. It was used at the beginning of the 19th century to prove that light exhibits wave properties. This experiment exploits two specific properties of waves.
