pipes
Sound
of different musical notes are emitted by hitting the
various pipes in the exhibit. The frequency or pitch
of the sound depends on the length of the air column
in the pipes. The shorter the length of air column,
the higher is the pitch.

Eye
as an Aperture
This
exhibit demonstrates that eye pupil diameter becomes larger
or smaller when light intensity is low or high respectively
like an aperture of a camera |

Stereo
hearing
The
exhibit demonstrates that our ears can detect the direction
of sound even if the time difference between the sounds
reaching either of the ear is as low as 1/2000th of a
second. If the sound arrives at both ears at exactly the
same time, we interpret the sound as coming from either
in front or behind us. |

Is Light Visible?
This
exhibit demonstrates that light is a form of energy that
makes things visible when it falls on them but by itself
it is invisible. |

Transfer
of Momentum
The
exhibit demonstrates in an interesting way the principle
of transfer of momentum by a group of seven hanging balls.

Swing
the Pendulum |
|
Sympathetic Swing (X, Y & Z -Axis)
This
exhibit consists of three sets of two pendulums each.
It demonstrates as to how the motion of the first pendulum
is transferred to the second through the connecting strips/springs.
When the oscillation of second pendulum is just in opposite
phase to that of the spring, it stops and when it is in
the same phase, it has maximum swing. |

|
Chaos
This
exhibit demonstrates that the oscillations of the pendulums
with bobs of asymmetrical shape create unpredictable oscillatory
movement and therefore do not follow the rules of simple
harmonic motion. |

Curie
Point
The
exhibit demonstrates the principle of curie point of the
material i.e., the temperature at which magnetic material
undergoes structural change to become non-magnetic |

|
| Grand
shuttle
The
exhibit demonstrates the repulsion property of electromagnets formed by energising the coil through a foot switch.
When a person walk over the switch, it energizes a coil
due to which upper end of the coil and the lower end
of the bobbin gains same polarity thereby repelling
each other resulting in movement of the shuttle to the
other end.

Lazy
Channel
The
exhibit shows that a magnet rolling along aluminum channel,
which acts as a single turn coil, induces a strong short-
circuiting current in it. This current gives rise to another
magnetic field, which opposes the field of the rolling
magnet, thereby slowing down its downward movements. |
