Alpha and beta are not electromagnetic radiation.
Alpha Gamma was created in 1867.
The main difference between gamma rays and infrared rays is in their wavelengths. Gamma rays have the shortest wavelengths while infrared rays have longer wavelengths. Gamma and infrared rays are types of electromagnetic radiation.
Gamma Alpha's motto is 'Γνωθι την 'Αληθειαν'.
Alpha Beta Gamma was created in 1970.
Alpha Delta Gamma was created on 1924-10-10.
Alpha Gamma Omega was created on 1927-02-25.
The motto of Alpha Gamma Omega is 'Fraternity for Eternity.'.
An "alpha ray" is not actually a ray at all, as a ray usually means "electromagnetic radiation". The closest yo can get to that is a stream of alpha particles. Alpha particles are helium nuclei (two protons and two neutrons bound together) stripped of their electrons; because they are heavy and relatively slow, they can be stopped typically by a sheet of paper. Infra red rays are electromagnetic radiation, like light or radio, at a frequency which we perceive as "heat".
Gamma Zeta Alpha was created on 1987-12-03.
Alpha Kappa Gamma was created on 1959-12-28.
Phi Alpha Gamma was created on 1894-03-25.
Alpha Gamma Rho was created on 1904-10-10.
