• Geometric Optics Experiment Set Optical Lens Kit Convex Concave Lens Light Refract Reflect Physics Teaching Kid Science Gift Notes 1 Lens materials is plastics 2 Light depth is strong! Don't appearance directly at the beam! Suitable for kids aged 6 and above, yet should be accompanied through an grownup to be used Kids by myself can not use it for safety reasons! 3 Light supply would not include batteries for transport safety Please practice 2 items of AAA batteries to be used 4 Lens edges can't be 100% smoothful and there might be molding marks at the lens surface throughout producing, ut it would not impact regular use or influence the sunshine direction Introduction This optics lenses set is especially used in physics education to assist college students learn mild refraction and reflection rules It involves 1 piece of biconcave lens, three items of biconvex lenses, 1 piece of plano-concave lens, 1 piece of plano-convex lens, 1 piece of oblong lens, 1 piece of triangular prism, 1 piece of multifunctional reflect and a 3-way mild source Students can note mild refraction in lenses of alternative shapes The multifunctional reflect has four facets which can gift light reflection on flat mirror, curved reflect and diffuse reflection on rough floor Specifications Item name: Optics Teaching Lens ( Spherical lenses, Plano lenses, Triangular Prism, Rectangular Lens) Lens material: Acrylic plastics Lens size: 60*20*6mm Lens quantity: 8 lenses and 1 reflector Light source: 3-way light source Uses: exploring the refraction and reflection of light Applicable Experiments 1 travels in a instantly line 2 of sunshine 3 refraction four lens refraction five Lens Refraction 6 Mirror Reflection 7 mirrored image eight Mirror Reflection 9 Mirror Reflection What's in the field 1 lens 1 2 lens 2 3 lens 3 four lens 5 lens 6 lens 7 prism eight lens 9 light sources 10 reflector
