• A pinhole camera is a simple device without a lens, just a light-proof box with a small aperture.
• Light passes through the pinhole to project an inverted image on the opposite side.

• The boxes measure approximately 150 x 100 x 100 mm.

Reflection of light is the phenomenon in which light rays strike a surface and bounce back into the same medium instead of passing through it.

When a light ray hits a smooth, shiny surface (like a mirror or polished metal), it reflects in a definite direction. This type of reflection is called regular reflection. Rough surfaces cause diffuse reflection, where light scatters in many directions.

The Gravity Tower shown is a physics laboratory apparatus used to demonstrate and study free fall under gravity. It consists of a transparent vertical frame made of acrylic panels, allowing clear observation of motion. At the top, a release mechanism holds a small metal mass (often a plumb-bob–shaped weight) suspended by a thin thread or trigger system.

When released, the mass falls vertically through the tower solely under the influence of gravity. The open, clear structure ensures minimal air resistance and provides accurate visual tracking of the falling object. The apparatus is commonly used to measure time of fall, acceleration due to gravity (g), and to illustrate concepts such as uniformly accelerated motion.
