Sound Waves in Medical Imaging and Damping

Assertion (A): Sound waves can be used to explore the soft tissue of the human body.
Reason (R): Oscillations in the real world are usually damped.
 
(1) Both (A) & (R) are true and the (R) is the correct explanation of the (A)
(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(3) (A) is true but (R) is false
(4) Both (A) and (R) are false

Solution:

Ultrasound, a type of sound wave, is extensively used in medical imaging to view soft tissues, making Assertion (A) true. All real-world oscillations experience damping due to dissipative forces, so Reason (R) is true. However, (R) does not explain (A).
