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 B?
Im getting confused betwwen B and D.
Thank you

im not exactly sure but i agree with B

Yes the answer is B

The correct answer is B. Amplitude of the sound wave. The loudness of a sound is determined by the amplitude of the sound wave. Amplitude refers to the height or strength of the wave, which corresponds to the amount of energy being carried by the wave. A higher amplitude results in a louder sound, while a lower amplitude produces a softer sound. Factors like frequency (A), temperature (C), and density (D) do not directly determine the loudness of a sound.

The correct answer is B. Amplitude of the sound wave.

To understand why, let's break down the options:

A. Frequency of the sound wave: Frequency refers to the number of cycles of the sound wave that occur in one second and is measured in Hertz (Hz). While frequency affects the pitch of a sound (how high or low it sounds), it does not directly determine the loudness.

B. Amplitude of the sound wave: Amplitude refers to the maximum displacement or distance a particle in the medium (such as air) moves from its equilibrium position as the sound wave passes through it. In simpler terms, it measures the strength or intensity of the sound wave. The greater the amplitude of a sound wave, the louder the sound will be.

C. The temperature of the medium: While temperature can have indirect effects on sound (such as affecting the speed of sound waves), it does not directly determine the loudness of a sound.

D. The density of the medium: Similar to temperature, density can have indirect effects on sound waves (such as affecting the speed of sound waves), but it does not directly determine the loudness.

Therefore, the correct answer is B, the amplitude of the sound wave. The greater the amplitude, the louder the sound will be.
