Answer:
The length of the open closed pipe is 12.25 cm
Explanation:
In open - open organ pipe, third harmonic has Antinode to Node, Node to Node, Node to Node and Node to Antinode.
The length of the open-open organ pipe is equal to the sum of wavelength in Antinode to Node, Node to Node, Node to Node and Node to Antinode.
L = A→N + N→N + N→N + N→A

In open-closed pipe, Fundamental frequency has Antinode to Node.
Thus, length of the open-closed organ pipe is equal to the wavelength in Antinode to Node.
L = A→N

From the information in the question, fundamental frequency of open-closed pipe is to the third harmonic of the open-open pipe.
F₀ = F

Therefore, the length of the open closed pipe is 12.25 cm

The Circuit Diagram is connected in a reverse bias attached below.
<h3>What is Reverse Bias? </h3>
Reverse biased p-n junction diode refers to the method by which a p-n junction diode stops electric current in the presence of applied voltage.
The positive terminal of the battery is connected to the n-type semiconductor material in a reverse biased p-n junction diode, while the negative terminal is connected to the p-type semiconductor material.
