DJCFWAF Optics Experiment Ray Box and Lenses Light Refraction Reflection Demonstrator Physical Optics Laboratory Equipment Total Reflection Foldable Disassembly Teaching Aid Instrument

Features

• Optical experiment kit, which demonstrates the laws of light reflection and refraction, suitable for junior high school physics teaching.
• By adjusting the angle between the light emitted by the light source and the normal of the demo screen, various incident and reflection phenomena can be seen.
• Insert the light source into the light source holder and move the shaft on the image surface of the condenser. At this time, the light emitted by the light source is the strongest, which is similar to parallel light and can be experimented.
• Overall size: 276*100*170mm; the radius of the demonstration screen >=130mm; the radius of the semicircular glass refractor >=35mm.
• This set of optical experiment apparatus is of premium material, durable and practical.If you have any questions, please write to us and we will be happy to help you.
