Click For Summary
An antinode occurs at the open end of an organ pipe due to the relationship between displacement and pressure in standing waves. At the open end, there is a displacement antinode, allowing maximum particle movement, while simultaneously creating a pressure node since gas can freely move in and out. This means that at the open end, there is no pressure buildup, as the gas is unconfined. Understanding this concept is crucial for grasping the behavior of sound waves in organ pipes. The dynamics of particle movement and pressure distribution are key to this phenomenon.
The answer is (B) but I don't really understand why.
Based on formula of Young Modulus:
$$x=\frac{FL}{AE}$$
The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A##
I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
