COUPLED PENDULUM

Demonstrates how energy is transferred from one body to another having the same natural frequency. The vibrations which occur in this case are sympathetic vibrations.

DOUBLE CONE

To the casual observer, the cone appears to defy gravity as it rolls uphill on the ramp.
If however, you keep track of the cone's centre fo gravity, you will see that it does not in fact violate the laws of physics.

The widening ramp permits the cone's centre of mass to drop slightly as the cone rolls up the ramp.

CYCLOID PATH

Demonstrates the effect of gravitational force is more on an object moving down a curved surface than on one on a straight inclined surface. Comes with all metal assembly consisting of inclined straight path and a cycloid path and two S.S. balls of the same mass.

DEPTH PERCEPTION

Demonstrates that perception of depth is not possible when viewed with one eye. The assembly is made with plastic rods which are fixed on a metal base. It consists some disjoint parts of an object and 'L' shaped plastic stand with a peep hole for observation. When you observe the disjoint parts of an object through the peep hole you will find a definite object in it.

LATERAL SHIFT

Demonstrates that light ray refracts and deviates from its original path when it passes through the prism.
Apparatus consists of a rectangular metal assembly with five holes at the top to insert coloured rods. Upper half portion of the rectangular frame is covered with metal sheet. Apparatus comes with a set of five coloured rods and a wooden block with two prisms fitted into it for observation.

one object eleven image

An interesting model which explains the application of properties of multiple reflections. Four acrylic mirror pieces are arranged in mutually perpendicular to each other on a metal base. When observation rod is placed at the centre of the model, you can see its images formed, which you can count.

persistance of vision

This simple model demonstrates that the human eye retina retains the images of an object for only 1/16 th of a second. If another images cast on the retina within this period both the images are super imposed and we see the combined image of the two. The model comes with five different combinations of picture.

linear or circular

This pendulum and filter experiment demonstrates that a pendulum swinging in one plane ‘appears to have an elliptical path when viewed with a neutral density filter in front of one eye. This was first noted by Pulfrich and the phenomenon is called a Pulfrich effect. This illusion is caused due to the perceptual mechanism in the eye. The use of neutral density filter in front of one eye creates distortions in the perception of the depth, size, velocity and position.
