Simple Physics Projects  The Founders of Simple Physics ProjectsSimple physics projects have been there from time immemorial. Today in this article, I highlight the outstanding and significant projects of all times.

In 1924 a French physicist by the name Louis de Broglie proposed that electrons and other discrete bits of matter, which until then had been conceived only as material particles, also have wave properties such as wavelength and frequency.

Later (1927) the wave character of electrons was proved the lab by C.J. Davisson and L.H. Germer in New York and by G.P. Thomson in Aberdeen, Scot.

To give details the idea, to outsiders and themselves, physicists often used a thought experiment, in which Young’s double-slit demonstration is repeated with a beam of electrons instead of light. Obeying the laws of quantum mechanics, the stream of particles would split in two, and the smaller streams would interfere with each other, leaving the same kind of light- and dark-striped pattern as was cast by light.

 

Simple Physics Projects on Waves

Particles would act like waves. According to an associated editorial in Physics World, from the magazine’s editor, Peter Rodgers, it wasn’t until 1961 that someone (Claus Johnson of Tübingen) carried out the experiment in the real world.

 

Robert A. Millikan in 1909 performed Oil-drop experiment. It was the primary straight and convincing measurement of the electric charge of a mono electron. Millikan was an American physicist. He sprayed tiny drops of oil using a perfume atomizer into a transparent chamber. The red animated metal plate made the positive plate while the blue made the negative.

 

The Speed of Waves in the Simple Physics Projects

The speed of droplets motion could be regulated by altering the voltage on the plates since as each droplet traveled through the air it picked up a slight charge of static electricity.

 

Electrons from the air acquire a negative charge when the space between the metal plates is ionized by a radiation because the electrons attach themselves to oil droplets.

 

Millikan varied voltage and observed one drop after another but there was no effect. That’s when he concluded that charge could only assume specific fixed values.  Charge of a single electron was the smallest of these portions.

 

One of Newton’s Simple Physics Projects

The same year Galileo died, another scientist was borne, and he was Isaac Newton. He also did many Simple Physics Projects.  After graduating in Trinity College, he started experimenting on the properties of light at home. He later became the first to decompose light using a prism.

 

The hypothesis that white light is the purest form by Aristotle was altered by Newton. Using a glass prism, he could demonstrate his experiment by shining a beam of sunlight through it. The beam decomposed into a spectrum which was cast on a wall.

 

Before, rainbows were considered more of abbreviation. Isaac concludes that the fundamental colors of the rainbow were yellow, green, orange, blue, indigo and violet.

Basically, there are more to enumerate more of this Simple Physics Projects, but I bet to stop for now.
