यदि ध्वनि संकेत के आने जाने का समय दुगुना हो जाए और जल में ध्वनि गति समान रहे तो गणितीय रूप से गहराई पर क्या प्रभाव पड़ेगा?

If the two way travel time of a sound signal doubles while sound speed in water remains constant what happens mathematically to depth?

Explanation opens after your attempt
Correct Answer

B. गहराई दुगुनी होगीDepth doubles

Step 1

Concept

Depth depends on \(d=\frac{vt}{2}\) so doubling time doubles depth. Exam tip: remember that two way time is divided by two.

Step 2

Why this answer is correct

The correct answer is B. गहराई दुगुनी होगी / Depth doubles. Depth depends on \(d=\frac{vt}{2}\) so doubling time doubles depth. Exam tip: remember that two way time is divided by two.

Step 3

Exam Tip

गहराई \(d=\frac{vt}{2}\) पर निर्भर करती है इसलिए समय दुगुना होने पर गहराई भी दुगुनी होती है। परीक्षा में आने जाने के समय में दो से भाग देना याद रखें।
