friends for their unwavering encouragement and
assistance during the course of this project. Their
motivation and belief in our abilities have been a source
of strength throughout this journey.
Finally, we are grateful to all those who directly or indirectly
contributed to the successful realization of this
endeavor. This project has been a remarkable learning
experience, and we owe its success to their collective
efforts.
GROUP INTRODUCTION
We, Group B, consist of five students working together to determine the refractive index of
various fluids using a hollow prism. Our combined efforts have been crucial in the success of
this project.
Smruti Swarup: Leading the group, Smruti has focused on the theoretical aspects and
cal cu la t io ns .
Chandrakant Jena: Chandrakant contributed to setting up and executing the experiment.
Jagdish Prasad Mohanty : Jagdish has been responsible for accurate data collection and
a na ly si s.
Sandeep Kumar Jena : Sandeep helped optimize the experimental process and ensure reliable
results.
Amit Kumar Biswal : Amit organized the documentation and presentation of our findings.
Together, we aim to deepen our understanding of optical phenomena and present our findings
effectively through this project.
