Question
The document compares the inverse-square variation of sound intensity with distance to the behavior of which other physical fields?
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... as the energy sent out at the source is constant... spreads out spherically very much as the electric field of a point charge or the gravitational field of a mass spread out.'
Hint
Think of fundamental forces that diminish in strength as the square of the distance from their source.
