Answer: The correct option is "Increased intensity means increased loudness".
Step-by-step explanation:
The energy of the wave is directly proportional to the square of the amplitude. Higher the energy of the wave, higher the amplitude of the wave. Lower the energy of the wave , lower the amplitude of the wave.
Loudness depends on the amplitude.The sound can be loud or soft. It depends on the intensity of the sound.
Therefore, Increased intensity means increased loudness.
