Download Solution PDFসঠিক উত্তর হল 22600 Hz
Key Points
- প্রদত্ত:
- শব্দের গতি (v) = 339 মিসে-1
- শব্দের তরঙ্গদৈর্ঘ্য (λ) = 1.5 সেমি
- λ = 0.015 মি
- শব্দের গতি(v) = তরঙ্গদৈর্ঘ্য (λ) x কম্পাঙ্ক (f)
- \(f ={v\over{λ}}\)
- \(f ={339\over{0.015}}\)
- কম্পাঙ্ক = 22600 Hz
Additional Information
- মানুষের জন্য শ্রবণযোগ্য শব্দের কম্পাঙ্ক 20 Hz থেকে 20,000 Hz এর মধ্যে থাকে।
- যেহেতু প্রদত্ত শব্দের কম্পাঙ্ক 20,000 Hz এর বেশি তাই এটি শ্রবণযোগ্য নয়।
