The intensity of the sound wave is defined as the ratio between the power of the wave and the area through which the wave passes:

where
I is the intensity
P is the power
A is the area
If we use the data of the problem,

and

, we find the intensity of the sound wave:
Answer:

Explanation:
The location, orientation, size, and type of image formed by a convex lens are related to the position of the image location in front of the lens
Object >2·F = The image formed by a convex lens when the object is located more than twice the focal length from the lens
Object < F = The image formed by the convex lens when the object is located between the lens and the focal length
