Year 1 Physics Lab

We make physics more real. In this lab, first year physics undergraduates gain practical experience in the working concepts of mechanics, optics, vibrations, waves, electricity, magnetism and quantum physics.

All experiments are designed to complement the first year theoretical physics courses, allowing students to understand how physics principles lie at the core of seemingly mundane events and observations in daily life, such as collisions, moving body dynamics, etc.

Our team also provides equipment for teaching and physics demonstrations to faculty, staff, and students. The laboratory is also a venue for special workshops for education and outreach.


We are located on Level 2 in the SPMS Building (SPMS-PAP-02-08).
