PH-211 Laboratory Physics 2
The objective of this module is for students to carry out a range of physical measurements and to collate data in a structured manner. Students will be familiarised with various software packages for the collation, analysis and representation of data. They will be expected to keep neat and comprehensive laboratory notebooks, and to write lucid reports of their experiments. The students will also get experience of working within a team (or group) environment on a five-week project.
