Introduction:
A mirage is an illusion which often occurs naturally. The kind most commonly produced by the
refraction of light when it passes into a layer of warm air lying close to a heated ground surface. This is an example of gradient index optics.
Driving Question:
Why does it seem as if the pig is where we can touch it but in fact we really can't?
Materials:
Mirage 3-D Hologram Maker
Procedure:
1) Participants will be asked to try to grab the "object" without being told that it is an illusion
2) Cover will be removed and participants can see the object on the bottom of the pan
Scientific Principle:
Mirage, creates real images of objects using two concave parabolic mirrors.
A system of concave mirrors produces real images of objects placed inside it as if they were sitting on top of the device.
Aim a narrow beam of light from a penlight or laser at the image. The spot on the image where you aimed the light is illuminated.
When we ray trace a model of the Mirage device, the real image of an object at the bottom is produced by rays that reflect off both parabolic.
Refraction-In this experiment, refraction is something that often occurs when waves travel from a medium with a given refraction index.
Reflection-In this experiment, light reflection from either side of the mirage contribute to the experiment "occurs whenever light travels from a medium of a given refractive index into a medium with a different refractive index."
Three-Dimension-In this experiment, three-dimension is the pig that shows up.
Illusion-A mirage is an illusion in itself because it shows the pig as a real 3D object
