Investigating the Emission and Absorption of Infrared Radiation Based on Surface Nature

The video explores how the emission and absorption of infrared radiation depend on the surface's nature. It includes two experiments using copper beakers to study emission and absorption, and a more advanced experiment with a Leslie Cube. The findings suggest that dark and rough surfaces emit and absorb infrared radiation better than light and smooth ones.

Explain how the Leslie Cube experiment is conducted and what it aims to demonstrate.

What conclusions can be drawn about the relationship between surface characteristics and infrared radiation emission?
