LAB PREP #7

what are the answers for #1 and #2

First drop down box is
m=1,2,3,4
Second one is
sin and tan
Third one is
angle in radians

still working on the rest...

decreases

decrease

closer together

increase

further apart

never correct

always controls

falls off

in the central diffraction maximum

decreases

more spead out

most

best row

more than

better

m*lambda = b*x/D

s = (D*lambda)/b

b = (D*lambda)/s

rel error = sqrt(((DeltaD/D)^2)+((Deltas/s)^2))

[b]still can't get #1??

What is the zero measurement of the micrometer? -.01 mm
What is the measurement for the hair? .08 mm

What is the diameter of the hair? ______
I don't know the answer to this part yet

Estimate the error in the measurement of the hair. .01 mm

just adding on to Kathleen, to get the diameter, it's .08 + 0.1

so answer is .09 mm

good work everyone heheh

For # one my answers were as follows:
-10 um
80.0 um
diameter 0.08 mm
error 0.01 mm
these are posted in the order in which they were asked.

What is the diameter of the hair? 0.09 is the answer.
