Reflection from Dielectrics
Third Year Laboratory, School of Physics, The University of New South Wales, Sydney, Australia
This programme will plot your data. It returns the results in the form of a graph containing your datum points and the calculated fit.
Details of Experiment:
Polarisation of beam with
respect to the plane of incidence
Refactive index of dielectric
Select data entry format
theta I (no errors)
theta I dI (I errors only)
theta d(theta) I dI (x & I errors)
theta=angle of incidence (in degrees), I=intensity of reflected light
d(theta)= error in theta, dI = error in I
Note: Use spaces between each entry. Enter the angle of incidence theta (in degrees) and reflected intensity I. Place one datum point per line.
(Hints: Tabs and commas may also be used to delimit values. You may "cut and paste" a list of data points onto this window.)
