Quran documented Photoacoustic phenomena 1300 years before Alexander Graham Bell (1880)
Quran 15:26 “… And certainly We created man of clay that gives forth sound, of black mud fashioned in shape..”
In making reference to smectite, a quartz clay which has now been confirmed by scientists to be the most probable source of life.
Alexander Bell figured it out in 1880:
Alexander Graham Bell (1880) reported the photoacoustic effect for the first time writing: [1] “..thin disks of very many substances emitted sounds when exposed to the action of a rapidly interrupted beam of sunlight..” The sound production from those solid samples resulted from the absorption of the infrared part of the solar energy spectrum.
