How to Calculate the Fundamental Frequency of an Open-Open Tube Filled with 0°C Helium?

What factors determine the fundamental frequency of an open-open tube filled with helium?

1) Length of the tube
2) Speed of sound in helium

Answer:

The fundamental frequency of an open-open tube filled with helium is determined by the length of the tube and the speed of sound in helium.

When calculating the fundamental frequency of an open-open tube filled with 0°C helium, there are specific factors that need to be considered. The length of the tube and the speed of sound in helium play crucial roles in determining the fundamental frequency.

The fundamental frequency can be calculated using the formula:

Fundamental frequency = Speed of sound / (2 * Length)

At 0°C, the speed of sound in helium is approximately 965 m/s. Therefore, if the tube length is 0.240 m, the fundamental frequency would be:

Fundamental frequency = 965 / (2 * 0.240) = 2300 Hz

By understanding these factors and using the formula provided, you can easily calculate the fundamental frequency of an open-open tube filled with 0°C helium.
