["【Included】1×Double Convex Lens,1×Double Concave Lens,1×Acrylic Glass Block,1×Triangular Prism,1×Concave-Convex Lens,1×Semicircular lens,1×Three Way Linear Light Source,1×plastic storage box, 1×360°Angle Diagram,1×English Color page manual.","【Magnetic Design】 They are all magnetic designs that can be demonstrated on a blackboard or whiteboard. It Comes with a plastic storage box and easy to store or carry. It is perfect for friends and classmates as a party birthday gift.","【the optical refraction and reflection experiments】plane mirror reflection, diffuse reflection, convex mirror reflection, concave mirror reflection, refraction of light, convex lens refraction, lens refraction, trigonometry refraction.","【master the physical optics of refraction and reflection knowledge easily】the physical optics experiment set can clearly show the light from a medium into another medium, the direction of propagation changes, so that the light at the junction of different media deflection phenomenon, and light propagation to different substances, in the demarcation plane to change the direction of propagation and return to the original phenomenon in the material.","The three-beam light source can be adjusted easily to change the direction of the light to make the light sources parallel. without battery（You need to configure 2 AAA batteries yourself）"]
