Inside an organ pipe that is open at both ends, the waves present are
Options
- Atransverse stationary waves
- Blongitudinal stationary waves
- Clongitudinal travelling waves
- Dtransverse travelling waves
Correct answer
B. longitudinal stationary waves
Step-by-step solution
Sound waves travelling in a gas (such as air inside an organ pipe) are longitudinal waves.
When these longitudinal waves travel through the pipe and reflect from its open ends, the incident and reflected waves superpose.
This superposition of two identical longitudinal waves travelling in opposite directions results in the formation of longitudinal stationary (standing) waves.
