What is a gamma ray and how is it represented?
A gamma ray, also known as gamma radiation (symbol γ or. ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves, typically shorter than those of X-rays.
What’s the charge of a gamma ray?
Gamma rays ( ) are electromagnetic waves, rather like X rays and radio waves. Thus gamma rays have no mass and no charge.
Is a gamma ray positive or negative?
Radioactive Decay As previously indicated, large unstable atoms become more stable by emitting radiation to get rid of excess atomic energy (radioactivity). This radiation can be emitted in the form of positively charged alpha particles, negatively charged beta particles, gamma rays, or x-rays, as explained below.
Is gamma a Greek letter?
Letter. Lower-case gamma, the third letter of the modern Greek alphabet. Its name is γάμμα or γάμα and it represents either a voiced velar fricative: /ɣ/ or a voiced palatal fricative: /ʝ/; before velars, it represents a velar nasal: /ŋ/. It is preceded by β and followed by δ.
What is the electron symbol?

What is a gamma ray made of?
A gamma ray (g) is a packet of electromagnetic energy (photon) emitted by the nucleus of some radionuclides following radioactive decay. Gamma photons are the most energetic photons in the electromagnetic spectrum.
What is gamma frequency?
The gamma frequency band is roughly defined as being between 30 Hz-100 Hz, with the 40 Hz point being of particular significance.
What are gamma rays made of?
Gamma rays (γ) are weightless packets of energy called photons. Unlike alpha and beta particles, which have both energy and mass, gamma rays are pure energy.
Do gamma rays affect humans?
Gamma rays can pass completely through the human body; as they pass through, they can cause damage to tissue and DNA..
