Size does matter...demonstrate the principles of optics and mirrors.
These extra-large parabolic mirrors make demonstrating optical principles a snap. One example? The concave mirror can demonstrate the reflection and focusing of light, heat, and even sound. A discussion of shapes and uses of satellite dishes can be visually demonstrated. The mirrors' extra-large size makes your demonstrations easy to see and understand, even from the back of the lecture hall.
Each aluminized mirror measures 24" in diameter and is supplied with an aluminum frame, mounting bracket, and base. The surface has been highly polished for accurate reflection. Order them and see why Professor Peter Kinsler of Howick College said, "I recommend them unreservedly to all physics and science teachers." Includes demonstration guide.
Activities and uses
Show the properties of convex and concave mirrors so everyone can see. A sample activity from the datasheet is given below.
Place an object upside down at a point just beyond the Focal Point (approximately 17 inches). An image will be perceived to be in front of the mirror. Place a screen with a platform at the point where the image appears. The image can only be seen by viewing along the principal axis and it will appear as though the doll is standing on the platform. Viewing away from the principal axis will reveal only a platform. An excellent demonstration and ideal for creating classroom discussion.
- In using this product, national and states science education standards are covered. Some examples are provided here. These are representative. However, check with your state to find the exact standards.
- Light interacts with matter by transmission (including refraction), absorption, or scattering (including reflection). To see an object, light from that object emitted by it or scattered from it must enter the eye.
- Explain how objects or media reflect, refract, transmit, or absorb light. Demonstrate wave interactions including interference, polarization, reflection, refraction, and resonance within various materials.
