Ultrasonic, Infrasonic and audible waves travel through a medium with speeds $V_u, V_i$ and V a respectively, then
Text Solution
Verified by ExpertsThe correct answer is:
C
Step 1: Identify the relationships among the speeds of ultrasonic ($V_u$), audible ($V_a$), and infrasonic ($V_i$) waves.
Step 2: The typical hierarchy for wave speeds is $V_u \geq V_a \geq V_i$.
Step 3: Among the options, Option C states that $V_u \approx V_i$, which is a special case of situations where the speeds of ultrasonic and infrasonic waves can be nearly equal under certain conditions.
This makes Option C the correct choice.
