According to the document, how does the 'loudness' change if the amplitude of a sound wave is doubled?
Options
A It becomes twice as loud.
B It becomes four times as loud.
Correct Answer
C It becomes half as loud.
D It remains the same.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The document states, 'Loudness is a factor of the amplitude of the wave. The Intensity of a sound wave is directly proportional to the square of its amplitude. If we double the amplitude of a wave, the sound is 4 times louder.'
