This experiment aims to determine the density of solid objects by measuring their mass and volume. The mass is measured using a balance, while the volume is determined either from the object’s dimensions (if it has a regular shape) or by water displacement in a graduated cylinder (if irregular). The......

This experiment demonstrates how to determine the focal length of a concave mirror by forming a real image of an object on a screen and measuring the distance between the object and the mirror pole. Radius – Concave mirror – Center of curvature – Light
