This apparatus is used to Verifying the Boyle’s law when air is decompressed and compressed. A horizontally mounted acrylic tube having a graduated scale (0- 300cm3) along one side. A gas tap closes the tube. Pressure gauge is present next to gas tap. By changing the position of rubber stopper, the effective length of the tube can be selected. The scale measures volume and pressure by means of pressure gauze. Boyle’s law is investigated by changing position of the stopper.
The versatile Optical bench kit is designed for comprehensive study of image formation, focal lengths, and image magnification. Featuring a 120 cm bench for precise lens alignment, the set includes essential components such as an LED letter F, object screen, two 200 mm focal length lenses (convex and concave), two 100 mm focal length lenses (concave and convex), and six mounts.
