A tuning fork vibrating at 256 Hz is near a closed pipe of length 0.33 m. The pipe is in resonance. What is the speed of sound?
Q1. A tuning fork vibrating at 256 Hz is near a closed pipe of length 0.33 m. The pipe is in resonance. What is the speed of sound?
Answer: 336 m/s
Explanation: For a closed pipe, the fundamental frequency corresponds to wavelength = 4 * length = 1.32 m. Speed = frequency * wavelength = 256 Hz * 1.32 m = 338 m/s, closest to 336 m/s considering rounding. Option A is incorrect due to slight miscalculation.
