Single bubble sonoluminescencc (SBSL) is the emission of light by an acoustically
trapped and periodically driven gas bubble collapses violently in the liquid medium. The
-'i-nsitv of light emitted by sonoluminescence (SL) bubble depends on the physical
pr:fscrties of the host liquid and also external conditions. Among these conditions,
i*rcrimental studies on SBSL in two inorganic acids, 60 wt% H:SOj and 50 \vt% H3PO4
conducted. These two inorganic acids have approximately similar viscosities in the
mr . mentioned concentrations. A photomultiplier tube was used to obtain intensity
gsttissrernents and the fiber optic spectrometer was used to obtain the spectral
pses5Kre™ents.
