Hi, a sound is perceived as louder when the amplitude increases.
If the amplitude of a sound wave increases, it means that the wave carries more energy. The Energy carried by a sound wave is related to the intensity of the wave.
If the sound wave has more intensity, it means that the sound is more intense (loud).
Answer : The correct option is, increase amplitude.
Explanation :
Amplitude : It is a measure of the size of sound waves.
The loudness of sound is depend on the amplitude of the sound wave. That means the more the amplitude, the louder will be the sound and the less the amplitude, the low will be the sound.
The loudness of sound does not depend on the tension and wavelength.
Therefore, the correct answer is, increase amplitude.
The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.
