Question

The amplitude of a sound wave made 3.3 times greater will result in:

a) Increased loudness
b) Decreased pitch
c) Smaller wavelength
d) Decreased frequency

Answer 1

Increasing the amplitude of a sound wave will result in increased loudness.

Step-by-step explanation:

The amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound, and a smaller amplitude means a softer sound. When the amplitude of a sound wave is made 3.3 times greater, it will result in increased loudness. The increase in amplitude allows for more energy to be transmitted through the wave, resulting in a louder sound.
