Undergraduate Laboratory:
For me, laboratory work has been an essential part of my undergraduate physics experience, as it helps bridge the gap between theoretical concepts and real-world applications. While classroom lectures provide the foundational principles and equations of physics, the lab allows me to test these ideas in a hands-on environment. By performing experiments, I’ve gained a deeper understanding of fundamental phenomena, such as mechanics, electromagnetism, optics, and thermodynamics, through direct observation and measurement.
