Physics: Calculation on stationary wave in a closed tube having wavelength of 40cm (SS2)

Welcome to Model Physics Mathematics Lessons. In this lesson, i solve a stationary wave problem in a closed tube (closed organ pipe) where the length of the tube is given by: L=3λ/4 This represents the first overtone (third harmonic) of a closed pipe. Remember: A node is formed at the closed end An antinode is formed at the open end Only odd harmonics are allowed in a closed tube, Given: λ=40 cm Substitute into the formula: L= 3 x 40 /4 Therefore, the length of the resonating column is 30cm. In this video, you will learn: -Why closed pipes support only odd harmonics -How L= λ/4, 3λ/4, 5λ/4 are formed How to quickly solve air column resonance questions in exams -Common mistakes students make in wave calculations Perfect for WAEC, NECO, JAMB, and secondary school physics exams. #goviral #physics #wavemotion #StationaryWaves #ClosedPipe #AirColumn #resonance #waecphysics #jambphysics #necophysics
