SUMMARY
The speed of sound in an organ pipe is influenced by factors such as temperature and density, with the average speed of air molecules at a displacement antinode being approximately 500 m/s in still air. The wave speed in an infinitely long organ pipe can be calculated using the formula v = sqrt(γRT/M) or v = sqrt(γP/ρ). The lowest possible frequency of a stationary wave in a 2.5 m long organ pipe is determined to be 90 Hz, calculated using the fundamental frequency formula fn = n f1. Understanding the relationship between pressure, temperature, and density is crucial for determining sound speed in gases.
PREREQUISITES- Understanding of wave equations, specifically y = A sin(kx - ωt)
