Question

Why is loudness of sound? What factors does it depends on?​

Answer 1

Answer:

Find the height of the point on the wall where the top of the ladder reaches. Let AB be a verticle wall and AC=10 m is a ladder. The top of the ladder reaches to A and distance of ladder from the base of the wall BC is 6 m . Hence, the height of the point on the wall where the top of the ladder reaches is 8 cm.

Answer 2

Answer:

The loudness of a sound depends on the amplitude of the wave. The loudness of sound is proportional to the square of the amplitude. The loudness of sound also depends on the sensitivity of the human ear. Note: Loudness is the measure of how strong a sound wave is at the place.
