What happens to the perceived frequency when both the source and the listener move with the same speed in the same direction?
जब स्त्रोत और श्रोता दोनों एक ही दिशा में समान गति से चलते हैं। तो अनुभव की गई आवृत्ति पर क्या प्रभाव पड़ता है?
Detailed Solution & Logic
It remains unchanged/यह अपरिवर्तित रहता हैं।
🟢 Explanation
- This situation is related to the Doppler Effect.
- When both the source and the listener move with the same speed in the same direction, their relative velocity is zero.
- Since Doppler Effect depends on relative motion, no change in frequency is observed.
👉 Therefore, the perceived frequency remains unchanged. - यह स्थिति डॉप्लर प्रभाव (Doppler Effect) से संबंधित है।
- जब स्रोत और श्रोता दोनों एक ही दिशा में समान गति से चलते हैं, तो उनकी सापेक्ष गति (relative velocity) शून्य होती है।
- क्योंकि डॉप्लर प्रभाव सापेक्ष गति पर निर्भर करता है, इसलिए आवृत्ति में कोई परिवर्तन नहीं होता।
👉 इसलिए, अनुभव की गई आवृत्ति अपरिवर्तित रहती है।
🔵 Extra Facts
-
- If the source and observer move towards each other, frequency increases.
- If they move away from each other, frequency decreases.
- यदि स्रोत और श्रोता एक-दूसरे की ओर बढ़ते हैं, तो आवृत्ति बढ़ती है।
- यदि वे एक-दूसरे से दूर जाते हैं, तो आवृत्ति घटती है।
❌ Other Options:
- It increases ❌
- It decreases ❌
- It fluctuates rapidly ❌
Final Answer: It remains unchanged / यह अपरिवर्तित रहता है
