Question

6. Loudness of a sound depends on
(a) frequency of vibrating object
(b) amplitude of vibrating object
(c) wavelength of vibrating object
(d) none of these​

Answer 1

loudness of a sound depends on its amplitude.

option b) is correct✔✅✅

Answer 2

Answer:

b)Amplitude of vibrating object

Explanation:

The amplitude of the wave determines the loudness of a sound wave. A larger amplitude means a loud sound while a smaller amplitude means a soft sound. If the amplitude is high then the sound will be louder and the sound will be feeble if the amplitude is low. Loudness is proportional to the square of the amplitude.
