Step-by-Step Solution:
Step 1 of 3

Solution 6P STEP 1: The decibel (db) is a logarithmic unit, which is expressed as used to describe ratio of two values of a physical quantity. In the question, we have asked to consider the intensities of the sound waves of 40 db and 30 db. As we know that intensity of classical waves is directly proportional to the amplitude of the wave, so let’s compare the intensities. STEP 2: The power ratio...
