Hand‑Held Manual Stroboscope [2555]

The Hand‑Held Manual Stroboscope is a simple but highly effective teaching aid designed to demonstrate the principles of motion, rotation, and apparent motion in physics lessons. It consists of a 255mm diameter hardboard disc featuring twelve evenly spaced 50 × 3mm slots, allowing clear observation of stroboscopic effects when viewed alongside moving objects.

The disc is pivoted on a smooth ball‑bearing mount, ensuring easy, controlled rotation with minimal friction. This mount also doubles as a comfortable hand‑held handle, making the stroboscope easy to hold, turn, and demonstrate in front of students. A built‑in finger hold further improves control and ease of use during demonstrations.

Robust, lightweight, and entirely manual, this stroboscope requires no power supply, making it ideal for repeated classroom use. Its straightforward design allows students to focus on the underlying physics concepts without distractions.

Key Features
