Answer:
I = 0.0631 W/m²
Step-by-step explanation:
Value in Decibel = 10 Log [tex]\frac{I}{10^{-12} }[/tex]
108 / 10 = Log [tex]\frac{I}{10^{-12} }[/tex]
10.8 = Log [tex]\frac{I}{10^{-12} }[/tex]
[tex]\frac{I}{10^{-12} }[/tex] = [tex]10^{10.8}[/tex]
I = [tex]10^{10.8}[/tex] x [tex]10^{-12}[/tex]
I = 0.0631 W/m²
