Question
The document states that the inverse-square law for sound intensity is analogous to the behavior of which other physical phenomenon?
Correct Answer
Option B is the correct answer.
Detailed Explanation
The text notes: 'Very much like the behaviour of the electric field of a charge. ... The energy spreads out spherically very much as the electric field of a point charge or the gravitational field of a mass spread out.'
Hint
Consider other phenomena where a quantity spreads out from a central point in 3D space.
