General Physics Experiment I
During the first semester of my freshman year, I took the General Physics Laboratory I course. In this course, I conducted nine in-class experiments (five of which were completed after class and four during class) and completed one independent experiment after class. My lab notes and experiment reports have been posted on this blog as follows. I welcome everyone to learn and exchange ideas with me!
In-class Experiments
those completed after class
Measurement of the Young’s Modulus of Metal
Determination of the Speed of Sound in a Medium
Resonance Phenomenon in an RLC Circuit
Quantitative Study of Light Diffraction
Observation of Dynamic Hysteresis Loop with an Oscilloscope
those completed during class
Adjustment of the Spectrometer and Measurement of Refractive Index by Grazing Incidence Method
Vacuum Coating
Measurement of Resistance Using a DC Bridge
Michelson Interferometer Experiment
Independent Experiment
By looking through a single water droplet, one can observe that the droplet acts as an imaging system. The magnification and resolution of such lens differs as the shape of droplet changes. The morphology of droplets on the object surface was analyzed, and the imaging principle and properties of the image were explored using geometric optics. The shape of the droplet and the imaging law were obtained. The ray trajectory was calculated using Python, confirming the positive correlation between magnification ratio and droplet volume, which is consistent with the theoretical formula.
