For my homework, i have to use this java applet and answer the 5 questions at the bottom. Now, i had no problem finding the period, frequency, or length of the tube in terms of the wavelength. But I'm really having troulbe finding the wavelength

This applet and how it is worded really confuses me. How am i supposed to find the wavelength of the wave my dragging the little microphone around inside the tube? it really doesn't make sense to me.

how can i find the distance between an node and an antinode by dragging the little microphone around?

can anyone give me a hint? Once i get the wavelength i can find the velocity, but if i don't get the wavelength i miss both problems.

wait i may have got it, is the distance between a node an and anti node simpy 1/26?.
Since there's a node at the open end, and an antinode at the closed end, and the tube is 1 m long, i should be able to count the number of nodes and antinodes and divide one by that answer to get the distance between a node and an adjacent antinode correct?
and then multiplying the distance between a node and an antinode by 4 would give me the wavelength?

I can understand your confusion with this applet and how it is worded. To find the wavelength of a sound wave, you need to measure the distance between two consecutive nodes or antinodes. The nodes are the points where the wave does not move and the antinodes are the points where the wave has the maximum displacement. By dragging the microphone around, you can measure the distance between these points and use that to calculate the wavelength.

To find the distance between a node and an antinode, you can drag the microphone to a node and then move it until you reach the next antinode. The distance between these points will be half of the wavelength. You can then use this value to calculate the full wavelength.

Additionally, you can also try adjusting the frequency of the sound wave and see how it affects the distance between the nodes and antinodes. This can help you to better understand the relationship between wavelength, frequency, and velocity.

I hope this helps and gives you a better understanding of how to use this applet to find the wavelength of a sound wave. Keep in mind that as a scientist, it is important to think critically and experiment with different methods to solve problems. Good luck with your homework!
