A beta particle, also called beta ray or beta radiation (symbol β), is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus, known as beta decay. There are two forms of beta decay, β − decay and β + decay, which produce electrons and positrons, respectively.

Review your understanding of wave properties in this free article aligned to NGSS standards. Key points: A wave is a repeating disturbance that travels through matter or space transferring only energy.
definition. A wave is a disturbance that propagates through a medium. There are three words in that definition that may need unpacking: disturbance, propagate, and medium. A disturbance, in the sense used in this definition, is a change from the current state of a measurable quantity at some location. For example….
