Crookes erradiometro

Crookes erradiometroa, argi-errota (light-mill) bezala ere ezaguna, beirazko bonbilla bat da, non huts partziala dagoen. Barruan, orratz batean muntatutako banderak daude. Banderak biratzen hasiko dira argia pizten denean eta areagotu egiten da argia handitzean, erradiazio elektromagnetikoaren intentsitatearen neurketa kuantitatiboa emanez. Biraketa honen arrazoia, historikoki, eztabaidagai zientifiko bizia izan da.^[1]^[2]

William Crookes kimikariak 1873. urtean asmatu zuen bere ikerketa kimiko batzuen ondorioz, aire korronteen eragina saihesten saiatzen zenean.
