Question

If the amplitude of a standing wave is doubled, the energy in the wave increases by a factor of
C) 1 
D) 2 
E) 4

Quizplus · Accepted Answer

The energy in a wave is proportional to the square of its amplitude. Doubling the amplitude will result in a four-fold increase in the energy (2^2 = 4). Therefore, the correct answer is E) 4.
