The radioactive material was kept in a small cavity in a block of lead. The whole apparatus was enclosed in an evacuated vessel as shown here. An electric field was applied. It was observed that the beam is split up into three components. The radiations, which emerged from the radioa..

Rutherford's Alpha-ray Scattering Experiment..

Rise in temperature in the 2 n d experiment is half that in the 1 s t experiment. Inference - Rise in temperature of a substance due to same amount of heat depends on the amount of substance tak..

Take half kg of water in a vessel. Note its temperature Heat it for exactly 2 minutes using a Bunsen burner. Again note down its temperatur..

Melde's Experiment - Melde's electrically maintained tuning fork consists of a large tuning fork (F) made of a ferromagnetic alloy, whose shank is rigidly clamped to a heavy rectangular wooden board (W). A bent strip of a metal is attached to one of the prongs of the fork and this serves ..

In 1819, Oersted first discovered the link between magnetism and electric current while lecturing to his students. The following circuit diagram depicts the rotation of a magnetic needle NS which can rotate freely about a vertical axis in a horizontal plane. On completing the circuit, the current f..

Take a few pieces of ice in a beaker. Insert a thermometer. Note the temperature. You will observe it to be 0 0 C. Now place the beaker on a flame and heat it. Ice starts melting. As you supply heat to ice, its temperature should rise. But you will find that the temperature of ice remains at 0 0 C..

Davison and Germer Experiment - The first experimental proof of the wave nature of electron was demonstrated in 1927 by two American physicists C.J Davison and L.H Germer. The basis of their experiment was that since the wavelength of an electron is of the order of spacing of at..

Faraday and Henry performed lots of experiments to learn about the connection between electricity and magnetism. The results of these experiments have led to the life styles of todays men, who made life easy by using lots of electrical application..
