Physics 107 - Light Intensity II

LEARNING GOALS


First, go through worked example II and answer all of the questions. Work in pairs on this and hand in when you are done.

THE EXPERIMENT

Goal is to to develop a model relating intensity to distance between the detector and lamp.

A few tips to get started:

PART I

PART II

PART III

PART IV

 

Marking Scheme

2 marks for worked examples at the start

2 marks for description of experimental technique, for your first measurements

2 marks for critique of first data and plan for more data-taking

2 marks for critique after your first log-log plot and plan for more data-taking

3 marks for total, final data set with uncertainty
2 marks for log-log plot of data

2 marks for plot of residuals
2 marks for conclusion, including function that describes the far-field data and comments on the near-field data.
