6A 10.20 - Lazer with Corner Mirror:

Demonstrates: Reflection of light.

Description: A laser is projected onto a corner mirror which reflects the light on all sides.

6A 10.30 - Plane Mirrors:

Demonstrates: Reflection and virtual images.

Description: Plane mirrors can be used to introduce the concept of ray tracing.

6A 10.40 - Folding Mirrors with Object:

Demonstrates: Reflection of light.

Description: Two large mirrors will give 360o reflected view of the object.

6A 20.10 - Bird in a Box:

Demonstrates: Reflection of light.

Description: Bird is upside down in the box but the mirror flips image to right side up.

6A 20.20 - Concave and Convex Mirrors:

Demonstrates: Reflection.

Description: These mirrors can give a virtual and a real image.

6A 20.40 - Large Spherical Mirror:

Demonstrates: Virtual and real images.

Description: At focal point image flips and goes from virtual to real.

6A 40.10 - Optical Disk I:

Demonstrates: Concave and convex lenses.

Description: Light enters one lens, is refracted then enters other lens and is refracted again.

6A 40.20 - Optical Disk II:

Demonstrates: Refraction of light.

Description: Light enters the lens and is refracted.

6A 40.41 - Invisibility Fluid:

Demonstrates: Index of refraction.

Description: A mixture of CCl4 and C6H6 has an index of refraction similar to Pyrex glass. When a rod of soft glass is placed in fluid, it can be clearly seen. When a pyrex glass rod is placed in fluid it becomes "invisible."

6A 44.10 - Chalkboard Optics:

Demonstrates: Light refraction.

Description: Light is beamed into the acrylic shapes which refract or reflect the light.

6A 44.20 - Total Internal Reflection:

Demonstrates: Internal reflection at proper angle of incidence.

Description: Set up with laser and green acrylic sheet on optical bench.

6A 44.25 - Total Internal Reflection with Prisms:

Demonstrates: Total internal reflection.

Description: A prism and a laser are used in this version of total internal reflection.

6A 44.30 - Total Internal Reflection with Microwaves:

Demonstrates: Total internal reflection.

Description: Prisms are used in this version of total internal reflection.

6A 44.40 - Fiber Optics:

Demonstrates: Total internal reflection with fiber optics.

Description: Fiber optics used for household decoration.

6A 46.10 - Rainbow with Acrylic Sphere:

Demonstrates: Light refraction.

Description: An acrylic sphere on a stand that represents a rain drop. Use a 100 W point source light for the Sun and project on East wall.

6A 46.20 - Solar Spectrum:

Demonstrates: Spectrum of the sun.

Description: The sun's image is brought into 103.

6A 60.30 - Microscope:

Demonstrates: Enlargement of an object.

Description: The filament of a lamp on a Variac is observed through lenses.

6A 61.20 - Fish Eye Camera:

Demonstrates: The concept of a camera.

Description: Same setup as the pinhole but a fish eye lens is added.

6A 61.30 - Pinhole Camera:

Demonstrates: Shows how a camera works.

Description: A polaroid setup is put on a tripod.

6A 65.10 - Camera Model:

Demonstrates: A real image.

Description: Image is inverted on the screen at end of optical bench.

6A 70.10 - Compound Microscope:

Demonstrates: Magnification of very small objects.

Description: A one person microscope.

6A 70.30 - Galilean Telescope:

Demonstrates: Telescopes.

Description: Use +100mm and +500mm Leybold lenses. Set up on large optical bench.

6A 70.40 - Newtonian Telescope:

Demonstrates: Telescopes.

Description: Use -100mm and +500mm Leybold lenses. Set up on large optical bench.

6A 70.50 - Projector Model:

Demonstrates: Shows how a projector works.

Description: A slide is projected on to a screen.
