How am I supposed to answer this question on the lab write-up? I have the date, but I don't know the formula or process to use. Thanks.

Organizing Data: Using your estimate of the threshold frequency from your first data table and your measured value of ft for sodium from your second data table, calculate the work function for both values. Plank’s constant is equal to 6.63 x 10-34 J • s.

To answer this question on the lab write-up, you need to calculate the work function using the threshold frequency and measured value of ft for sodium, and the given value of Planck's constant.

The work function (Φ) can be calculated using the formula:

Φ = planck's constant * (threshold frequency / ft)

First, you will need to find the threshold frequency from your first data table. Look for the value associated with the threshold frequency and record that value.

Next, go to your second data table and find the measured value of ft for sodium. Record that value as well.

Now, it's time to calculate the work function. Take the threshold frequency you found earlier and divide it by the measured value of ft for sodium. Multiply the result by Planck's constant (6.63 x 10^-34 J • s). The final value you get is the work function for both values.

Make sure to include all the relevant calculations and units in your lab write-up.

IT would be helpful to know what is in the data tables.

But of more concern, you ought to know what you are doing in a lab before you start, so that you have an idea of what is the purpose, what data you will collect, and how to analyze it. I am quite certain you did not do that before collecting data. In fact, I bet you had no idea of what you were doing in the lab at all. Are you paying for this course?
