Q. Ultrasonic, Infrasonic and audible waves travel through a medium with speeds $V_{u},V_{i}$ and $V_{a}$ respectively, then
A) $V_{u},V_{i}$ and $V_{a}$ are nearly equal
B) $V_{u} \geq V_{a} \geq V_{i}$
C) $V_{u} \leq V_{a} \leq V_{i}$
D) $V_{a} \leq V_{u}$ and $V_{u} \approx V_{i}$
Explanation
The correct answer is Option A: $V_{u},V_{i}$ and $V_{a}$ are nearly equal.
