Homework Statement

An intensity level change of +2.00 dB corresponds to what percentage change in intensity!

Homework Equations

B = dB = 10 log (I/Io)

The Attempt at a Solution

2.00 dB = 10 log (I/Io)
0.2 = log (I/Io)
I/Io = 10e0.2 = 1.585

Assuming Io = 1, then percentage difference = 100(1.585-1.0) = 58.5%.

Is this correct? Please help asap.
