|
To show that light is a wave |
• A single light source is placed behind a screen with one slit. • The light passes through this screen and encounters another, with two slits. • A third and final screen is going beyond this one |
|
|
To show that sound is a wave |
• A single signal generator is connected to two speakers, thus creating coherent waves |
|
|
To demonstrate atmospheric pressure |
• Set up the apparatus as shown. • Heat the can for a period with the lid removed, so that the water inside boils. • Remove the can from the heat and tightly replace the lid. • Let the can cool |
|
|
To demonstrate Archimedes Principle |
• Set up the apparatus as shown. • Hang the mass from the spring balance and note the reading. • Lower the mass into the water and again note the reading. • Find the weight of the displaced water |
|
|
To find the resultant of vectors |
• Set up the apparatus as shown. •Note the readings on the first two Newton-meters and note the reading on the third meter |
|
|
Using the ice and steam points to calibrate a thermometer |
• Place a thermometer in melting ice, as shown. • Mark the length of the column of mercury. • Place the thermometer in boiling water. • Again mark the length of the column of mercury |
|
|
To demonstrate an electric field |
• Add some semolina to a shallow dish of oil. • Attach electrodes as shown |
|
|
To demonstrate that a capacitor stores energy |
• Set up the apparatus as shown. • Allow the capacitor to build up charge. • Disconnect it from the generator and bring a conducting wire from each plate to the bulb |
|
|
To demonstrate the factors on which the capacitance of a capacitor depend |
• Set up the apparatus as shown |
|
|
To show the distribution of charge on an object |
• Bring a proof plane near to the dome of a charged Van de Graaf as shown. • Earth the side furthest from the dome (touch it) • Remove the connection to earth • Bring the proof plane to a gold-leaf electroscope, and check for charge. • Repeat at different points on the dome |
|
|
To demonstrate that a current-carrying conductor in a magnetic field experiences a force |
• Set up a circuit as shown, supporting the foil with a retort stand |
|
|
To demonstrate the principal on which the definition of the Ampere is based |
• Set up a circuit as shown, supporting the foil with a retort stand. • Switch on the current and observe what happens |
|
|
To demonstrate Electromagnetic induction |
• Set up a circuit as shown. • Move the magnet towards the coil |
|
|
To demonstrate Lenz's Law |
• Set up the apparatus as shown. • Move the magnet towards the loop and then away from it |
|
|
Rutherford's gold foil experiment |
• Rutherford fired a beam of alpha particles towards a thin sheet of gold. • Alpha particles are small, positively charged particles. • A detector told him where the alpha particles went |
|
|
Cockroft-Walton |
• The Cockroft-Walton experiment was the first splitting of the nucleus, using artificially accelerated particles. • In it, they fired protons at a lithium target. |
