Question

The INVERSE SQUARE LAW states that, "Sound intensity _________________ every time the distance is doubled

Answer 1

Drops by 6 db

Step-by-step explanation

The Inverse Square Law states that in a free field for every doubling of the distance from the source, the intensity of sound drops by 6 decibels. As the intensity of sound is inversely proportional to the distance squared.

The intensity of sound ∝ 1 ∕ distance squared.

I ∝ 1 / d2

Here, ∝ is ‘proportional to’

I is the ‘intensity of sound’

& d is the ‘distance from the source’
