Question

The inverse-square behavior of sound intensity is compared in the text to which other physical phenomenon?
Options
A The behavior of light intensity from a point source.
B The electric field of a charge or the gravitational field of a mass.
Correct Answer
C The decay of radioactive isotopes.
D The flow of current through a resistor.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The document states: '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

The text draws a direct analogy to fundamental force fields that spread out spherically.
