Question

Experiment I: Malus' Law Questions The orientation of these polarizing filters can't be measured with great accuracy because they re not marked off in small increments. Estimate the maximum uncertainty in measuring @ in this experiment. Justify your estimate. 1 with theory. Let's assume your 21 From your data table, choose the trial in poorest agre 1/1 measurement was accurate, but that the angle was not accurate. Calculate the angle that would theoretically yield this value of 1/1 measured angle. and compare it to the a Is the uncertainty in measuring 0 sufficient to explain the error in 1/I..Explain. b

Answer 1

(1) solan 8 from Malas law – Is To Cal20 – i Maximum uncertainty in measuring o -- I, CHO sino - ci) do dI – Io sinze – (1) do ao AI d I - I. Sin 20 - no do AO AI – in I sinao maximum Uncertainty - AI A mox = & AI I 20 Sin 202 20 Because for small 20 AI O may = AI -W) 2 I. O

(2) Solun & For Imax 0 = 0o in maluse low- Imoy - Io Cap?= I. (vi) Ir I. cor – i (from Malas' lan) Home I I, Coscopio then- carlo - I - Io Calze Imax Io Imox Colo = I Imax de cast ( 5 ) - City (8) I cono uncertainly if I let a Calzo Imax Imas then Joa o - (ix) dy=- Lead sino do – (x) 07 AJF – since to – sino so (xi) Imax

mous since for the measuring concertainty of the I we need to measure only no, it means measurung uncertainty of oil Bafficient to explain error in I/Imax.
