Скачать или смотреть RRB ALP & Technician 2026 | Physics: Wave Motion & Sound Wave | Complete Theory + Numericals

Dear Students! 🎓

RRB ALP (Assistant Loco Pilot) aur Technician 2026 ki taiyari kar rahe sabhi candidates ke liye ye video ek "One-Stop Solution" hai. Is lecture mein maine Physics ka sabse important chapter "Wave Motion & Sound Wave" zero level se advanced level tak cover kiya hai.

Is video ko dekhne ke baad aapko is topic se koi bhi doubt nahi rahega aur aap exams mein numericals ko asani se solve kar payenge.

📌 What We Covered in This Lecture:
1. Wave Basics: Wave ki definition aur uska propagation kaise hota hai.
2. Types of Waves: Mechanical vs Electromagnetic, Longitudinal vs Transverse waves.
3. Wave Parameters: Amplitude, Frequency, Wavelength aur Time Period (With Formulas).
4. Sound Waves: Sound ki property aur different mediums (Solid, Liquid, Gas) mein sound ki speed ka comparison.
5. Factors Affecting Speed: Temperature, Humidity aur Pressure ka sound par asar.
6. Important Phenomena: Echo (Pratidhwani) aur Doppler Effect ke concepts.
7. Characteristics of Sound: Loudness vs Intensity aur Pitch vs Frequency.
8. Numericals: RRB ke previous year questions par based important numerical problems.
