Demonstrates: Reflection of light.
Description: A laser is projected onto a corner mirror which reflects the light on all sides.
Demonstrates: Reflection and virtual images.
Description: Plane mirrors can be used to introduce the concept of ray tracing.
Description: Two large mirrors will give 360o reflected view of the object.
Description: Bird is upside down in the box but the mirror flips image to right side up.
Demonstrates: Reflection.
Description: These mirrors can give a virtual and a real image.
Demonstrates: Virtual and real images.
Description: At focal point image flips and goes from virtual to real.
Demonstrates: Concave and convex lenses.
Description: Light enters one lens, is refracted then enters other lens and is refracted again.
Demonstrates: Refraction of light.
Description: Light enters the lens and is refracted.
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."
Demonstrates: Light refraction.
Description: Light is beamed into the acrylic shapes which refract or reflect the light.
Demonstrates: Internal reflection at proper angle of incidence.
Description: Set up with laser and green acrylic sheet on optical bench.
Demonstrates: Total internal reflection.
Description: A prism and a laser are used in this version of total internal reflection.
Description: Prisms are used in this version of total internal reflection.
Demonstrates: Total internal reflection with fiber optics.
Description: Fiber optics used for household decoration.
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.
Demonstrates: Spectrum of the sun.
Description: The sun's image is brought into 103.
Demonstrates: Enlargement of an object.
Description: The filament of a lamp on a Variac is observed through lenses.
Demonstrates: The concept of a camera.
Description: Same setup as the pinhole but a fish eye lens is added.
Demonstrates: Shows how a camera works.
Description: A polaroid setup is put on a tripod.
Demonstrates: A real image.
Description: Image is inverted on the screen at end of optical bench.
Demonstrates: Magnification of very small objects.
Description: A one person microscope.
Demonstrates: Telescopes.
Description: Use +100mm and +500mm Leybold lenses. Set up on large optical bench.
Description: Use -100mm and +500mm Leybold lenses. Set up on large optical bench.
Demonstrates: Shows how a projector works.
Description: A slide is projected on to a screen.
