Sound Waves in Medical Imaging and Damping – Rankers Physics

Sound Wave and its Characteristics: Practice Problem & Solution

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

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Sound Wave and its Characteristics. Understanding the underlying formula is key to arriving at the correct answer below:

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).
