A contour plot of light intensity from a central point source
Open a new MathematicaŽ notebook and use your data from the CBLŽ activity
and copy
the data to the example function below.
![[Graphics:Images/IntensityGraphs_gr_1.gif]](Images/IntensityGraphs_gr_1.gif)
![[Graphics:Images/IntensityGraphs_gr_2.gif]](Images/IntensityGraphs_gr_2.gif)
Your contour plot of the data should look similar to the graph below.
![[Graphics:Images/IntensityGraphs_gr_3.gif]](Images/IntensityGraphs_gr_3.gif)
A graph of light intensity function E= .
Plot your CBLŽ data and explain the relationship between intensity and
distance.
Your graph should look similar to the one below.

A 3-D plot of light intensity from a central point source.
In order to see a 3 dimensional graph of your CBLŽ data, enter the data into
a Plot3D function.
![[Graphics:Images/IntensityGraphs_gr_7.gif]](Images/IntensityGraphs_gr_7.gif)
Your 3D plot should be similar to the one below.

Write a summary of the results that you got and discuss the relationships
between light
intensity and distance from light source. Predict what the values would
be given a different
light intensity (stronger or weaker) and what the graphs would look like.
