Introduction:

In the Malda College Model Competition held from January 4th to 6th, 2024, two distinct models were presented by the Department of Physics. The first model, focusing on the intriguing phenomenon of red sunsets, was developed by third-semester students. The second model, a Laser Security System employing Light Dependent Resistors (LDR), was crafted by first-semester students.

Model 1: Red Sunset Phenomenon (Third Semester):

The third-semester students delved into the scientific intricacies behind the captivating red sunset phenomenon. Their presentation showcased a profound understanding of atmospheric conditions and optical processes contributing to this natural spectacle. Visually engaging graphics complemented their articulate explanations, making for an enlightening experience for the audience.

Model 2: Laser Security System with LDR (First Semester):

The first-semester students showcased their skills by presenting a Laser Security System utilizing Light Dependent Resistors (LDR). Their model demonstrated the practical application of physics principles in a security context. The team effectively illustrated the system's functionality, emphasizing the integration of theoretical knowledge with technological implementation.

Collaboration and Learning:

The division of labor between first and third-semester students showcased a collaborative approach within the Department of Physics. While first-semester students engaged in a hands-on project, third-semester students explored a theoretical phenomenon. This collaborative effort not only facilitated mutual learning but also enriched the overall academic experience.

Presentation Dynamics:

Both teams demonstrated commendable communication skills during their presentations. The third-semester students' explanations of the red sunset phenomenon were enriched by their advanced theoretical understanding, while the first-semester students impressed with their practical application of physics in the Laser Security System. The diversity in presentation dynamics highlighted the department's commitment to a comprehensive physics education.

Audience Engagement:

The audience actively participated in the Q&A sessions, reflecting their keen interest in both models. Questions directed at the third-semester students delved into the complexities of atmospheric optics, while inquiries for the first-semester students focused on the technical aspects of the Laser Security System. The engaged audience demonstrated the success of both presentations in sparking intellectual curiosity.
