Leqhubu:● Moko oa puisano ke ho fetisa boitsebiso, haholo-holo ka mokhoa oa maqhubu.  ● Maqhubu a arotsoe ka maqhubu a mechanical, wave electromagnetic, matter wave le gravitational wave (quantum communication).  ● Liphoofolo le limela li ile tsa ithuta ho sebelisa maqhubu a molumo, khanya ea infrared le e bonahalang ka ho etsa lipatlisiso.

maqhubu a motlakase:

Hajoale, leqhubu le sebelisoang haholo la motlakase ke leqhubu la motlakase, le ka aroloang likarolo tse 'maloa ka kakaretso:

● Radio (R) (3Hz~300MHz) (TV, seea-le-moea, joalo-joalo)

● Microwave (IR) (300MHz~300GHz) (radar, joalo-joalo)

●Infrared (300GHz~400THz)

● Leseli le bonahalang (400THz~790THz)

● UV

●X-ray

● mahlaseli a gamma
