experiment

These experiments were conducted in detail by J.J. Thomson and he studied the passage of electricity through gases at extremely low pressure in a cylindrical glass tube. It was discovered that at extremely low pressure, gases become conductors of electricity and emit streaks of light, wh..

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..

Newton's Experiment - Dispersion of Light - Sir Isaac Newton, while studying the images of heavenly bodies formed by a lens, found that the image is colored at its edges. In 1665, to investigate this, he performed an experiment using a prism. Newton darkened his room at Trinity ..

Electromagnetic Induction - 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 applications. S..

Hershey and Chase devised an experiment in the year 1952 with two different preparations of T 2 phage. T 2 phage contains both DNA and proteins. It is possible to examine which of the two components has the information to programme for the production of more viral particle..

Aristotle, the great ancient philosopher performed some experiments to study the speed of freely falling objects. He observed that when two bodies of different masses were dropped simultaneously from the same height, the heavier object reached the Earth's surface earlier than the lighter ..

Take a clean and dry beaker and find it's mass (m) using a physical balance. Now find the weight of a stone by suspending it from a spring balance. Fill an Eureka can (Eureka can is a beaker having a spout near the top) with water filled till the spout. Place the beaker of mass 'm' under the spout...

Archimedes' Principle - The underlying fact on which the principle is based was discovered by Archimedes in about 300 B.C. The story goes that the King of Sicily suspected that the goldsmith has mixed some silver in his crown and cheated him. Without destroying the crown he wanted to know the truth..

Experiment to Demonstrate Interference of Sound Waves - Interference of sound waves can be demonstrated using Quincke's tube. It consists of two U-tubes ABCDE and FGH, whose limbs can be inserted telescopically into each other. The tube ABCDE is provided with two side tubes at B and D. Th..

An Experiment to Prove Newton's Third Law of Motion - Couple two spring balances A and B as shown in the figure. When we pull the balance B both the balances show the same reading indicating that both the action and reaction forces are equal and opposite. In this case, the pull of either ..
