Let's get the ball rolling please How are you guys getting the wavelength (m)? - i tried 1/ {(1/2^2)-(1/n^2)} with the value of (1/2^2)-(1/n^2) i thought that was (1/wavelength) which i tried entering into the appropriate column but only one lights up o.o any ideas on this? my values of m won't light up either, did you guys account for a distance difference? thanks

Lab 10 prep

Question 1: They give you N=100, and say the absolute error is sqrt(N) so absolute error = 10. By definition we know that absolute error is the relative error times the value (N), so to find relative error you just now divide by your value N(100) and you get .1 . If you complete the same procedure for the next two parts you get 31.62 and .03162. Question 2: All I have so far is: If x is in meters what are the units of the absorption constant ? 1/m Question 3: All ...

Error in y(M)

my value is 0.005 but my TA is really strict with these errors. should it be 1/2 millimeter since you take 1/2 smallest division of the ruler?

Lab 5 Execution

Does anyone know or understand the first question in the execution portion? I thought that the doubling of magnetic field is an overestimate and that the correct equation decreases the field. But I want to make sure, cus I don't have a clear explanation for these.

Thanks.

Was the direction of the motion of the needle consistent with the current you generated? Explain with reference to the way the winding on the coils is connected to the galvonometer terminals. (Type your answer for your TA to grade)

Does anyone understand this? I am so confused.
