Hwa Chong Junior College Student

Summary

I am a student from Hwa Chong Junior College, class 26S6H. I am effective at managing my time, prioritising tasks and meeting deadlines. I have a lot of free time so I use them for research.

Work History

2025 Research Project in School - Distinction

Research Project titled: "An Investigation on how the Coherence and Statistical Properties of Photons affect Photon Bunching using the Hanbury Brown and Twiss (HBT) Effect."

I learnt that photons can be bunched due the way they are generated. Photons generated by lasers arrive randomly in time. Photons generated by thermal sources generally arrive bunched. Photons generated by different light sources have different coherence and statistical properties.

2024 Research Project in School - Distinction

Research Project titled "Finding the magnification and resolution of an image formed by a water droplet lens."

I learnt how to characterise the resolution of a lens using the modulation transfer functions in fourier optics, starting from the generalised pupil function. Aberrations due to imperfections in the water droplet lens were characterised using Zernike Polynomials.

2023 Research Project in School - Distinction

Research Project titled "Using spectrophotometry to determine pollutants in water sources"

I managed to build a spectrophotometer instead of relying on commercially bought ones. I relied on Beer Lambert Law to determine the concentration of analytes in the solution that was being analysed.

Skills

    Throughout the many research experiments that I have conducted, I have learnt how to build and set up my own experiments accurately

    I have also learnt to persevere, especially when theoretical results do not match with experimental data

Accomplishments

    Singapore Young Physicists Tournament Category B in 2025: Silver Award

    I completed a report titled "Sound Versus Fire". The problem statement requires investigation into how a small flame can be put out by sound, and the relevant parameters that determine whether the flame will be extinguished.

    Singapore Young Physicists Tournament Category A in 2026: Bronze Award

    I completed a report titled "Magnetic Newton's Cradle". The problem statement requires the construction of a Newton's Cradle, using repulsing, non-touching magnets instead of the usual colliding balls, that can lead to interesting physics.
