Concave and convex lens
Concave and Convex Lenses are essential optical components used to manipulate light by refraction. A convex lens is thicker at the center and converges light rays to a focal point, while a concave lens is thinner at the center and diverges light rays. These lenses are fundamental in various scientific experiments, optical instruments, and educational demonstrations to study image formation, focal length, magnification, and light behavior. Manufactured with high-quality optical glass or plastic, they offer clarity and precision necessary for laboratory and industrial applications.
Gold Leaf Electroscope
Gold Leaf Electroscope is a sensitive scientific instrument used to detect and measure electric charge. It consists of a metal rod connected to two thin gold leaves enclosed within a glass container. When the rod becomes charged, the leaves repel each other due to like charges, indicating the presence and relative magnitude of electric charge. Gold Leaf Electroscopes are widely used in physics education, research, and experimental demonstrations to study static electricity and charge properties. The gold leaves provide high conductivity and flexibility, ensuring precise detection of electrical phenomena.
RING AND BALL THERMAL EXPANSION
Ring and Ball Thermal Expansion Apparatus is a precision laboratory device used to determine the coefficient of thermal expansion of materials, particularly metals. The apparatus consists of a metal ring and a steel ball of known dimensions. When heated, the metal ring expands, allowing the ball to pass through at a specific temperature. This temperature corresponds to the expansion point of the ring material. The device is widely used in physics and materials science laboratories to study the thermal properties of materials and to teach fundamental concepts of thermal expansion and heat behavior.
Van de graaf generator electrical
Product Description
The Van de Graaff Generator Electrical is a high-voltage electrostatic generator designed to produce static electricity and high potential differences for experimental and educational applications in physics laboratories. It operates by transporting electric charge to a hollow metal sphere using a moving belt, creating voltages up to several million volts. This device is widely used to demonstrate electrostatic principles, study particle acceleration, and conduct research in nuclear physics, materials science, and electrostatics. Built with durable insulating materials and precise mechanical components, the Van de Graaff Generator Electrical ensures reliable performance and safety during laboratory use.
