Verifying V=f? in Physics Lab: Calculating Frequency

[dvyu]

Homework Statement

I have had to do 6 labs for physics class, and i am now trying to write them up, but am a little confused. The first lab i did was to verify the equation v=f?. I yoused a generator to make a straight wave, and then put in a barrier to make a standing wave. I have to calculate the frequency, but don't know what formula i should be using.
the information my group took down was that there for 12 bright stripes, the distance was 24.2cm. and the frequency was 10Hz
but i just don't know what equation to use from there

Go to the text and first understand nodes and anti-nodes in the standing waves. What is the distance between two consecutive nodes and anti-nodes? what is the relation between wave speed and frequency?

As a scientist, it is important to ensure that all data and calculations are accurate and valid. In this case, it seems that you are trying to verify the equation v=f? through a lab experiment. To do this, you will need to use the correct formula and ensure that your measurements are precise.

Based on the information provided, it seems that you were able to observe 12 bright stripes within a distance of 24.2cm and have a frequency of 10Hz. To calculate the frequency, you can use the equation v=f?, where v is the velocity of the wave and ? is the wavelength. In this case, you already have the frequency (10Hz) and the distance (24.2cm), so you can rearrange the equation to solve for ?.

? = v/f = 24.2cm/(10Hz) = 2.42cm

This means that the wavelength of your wave is 2.42cm. From here, you can use this value to verify the equation v=f? by plugging it back into the original equation and checking if it matches the velocity of your wave.

It is also important to note that in order to ensure accuracy, you should repeat the experiment multiple times and take multiple measurements to calculate an average value for the wavelength. This will help to reduce any errors or uncertainties in your data.

In conclusion, to verify the equation v=f?, you can use the formula v=f? and ensure that your measurements are precise and accurate. Remember to repeat the experiment and take multiple measurements to calculate an average value for the wavelength.
