lab 2 help

Have you entered the formula for the "V_1-V_2" cell yet?

I was having problems to at first since my voltage was 1.528 VDC and lowest I used 0 as well.
V_1 should be your lowest, i.e. 0.
Perhaps 2 was too high, have you tried other values?

im having trouble just figuring out what my T1 and T2 values are... how is this done. I tried just reading it off my graph, but it keeps being marked incorrect.

c

During the experiment,
Function generator created sin graph.
So I thought that T1 and T2 should be similar.

But it sounds like, on the excel sheet, T1 is like 6.0E-5 amd T2 is like 3.0E-4.

How do people get this much difference from regular sin graph?

Isn't T1 is the wavelength of first curve and T2 for the last curve?

Error of T2-T1 is just sqrt ((T1)^2+(T2)^2)

My T1 is 1.0E-4, and T2 is 4.9E-4. My T2-T1 is 3.9E-4. To find error I did sqrt ((1.0E-4)^2 + (4.9E-4)^2) and got 5.001E-4. The worksheet isn't accepting my answer. WHAT AM I DOING WRONG? plz help
