Which of the following factors determines the loudness of a sound?
A. Frequency of the sound wave.
B. Amplitude of the sound wave.
C. The temperature of the medium.
D. The density of the medium.
Is the answer d?
Thank you
I think d is correct; however, I don't think that is the only one nor is it the primary one.
The answer is actually B
B. Amplitude of the sound wave.
Yes, the correct answer is B. Amplitude of the sound wave.
To determine the loudness of a sound, we need to understand the concept of amplitude. The amplitude refers to the maximum displacement of particles in a medium caused by the sound wave. In simpler terms, it is the size or intensity of the sound wave.
When a sound wave has a higher amplitude, it means that the particles of the medium are displaced to a greater extent. This results in a louder sound. Conversely, when the amplitude is low, the displacement of particles is reduced, leading to a quieter sound.
Frequency (A) refers to the number of cycles or vibrations that a sound wave completes in a given time, whereas temperature (C) and density (D) of the medium do not determine the loudness of a sound.
Therefore, the answer is B. Amplitude of the sound wave.
