The intensity of a certain sound wave is 6 $\mu$W/cm². If its intensity is raised by 10 decibels, the new intensity (in $\mu$W/cm²) is: A) 60 B) 6.6 C) 6.06 D) 600 E) 12

Question

Quizplus · Accepted Answer

The intensity of a sound wave is measured in decibels (dB). The decibel scale is logarithmic, which means that each 10 dB increase in intensity represents a tenfold increase in power. Therefore, if the intensity of a sound wave is raised by 10 dB, the new intensity will be 10 times the original intensity. In this case, the original intensity is 6 F1F1F1S1F1F1F10W/cm², so the new intensity will be 60 F1F1F1S1F1F1F10W/cm².
