It was probaly the light bulb which he did create even though some people say it was someone else!
contribution of nature of light in albert Einstein
Thomas Alva Edison used physics in many of his inventions, the light bulb, the large dynamo to make DC electricity, the phonograph, the 'moving pictures'.
wheat are the common properties and characteristic of light
Sir W. Crookes discovered the Properties of Light in 1879.
one of the properties of light is that light travel at straight line
He made electricity less expensive and more readily available
Not exactly - light has wave properties. That means that it behaves like a wave.
The simplest answer is that light consists of particles with wave properties. Elementary particles also have wave properties. This is how light travels.
Write down different properties of light and sound?
It can be reflected, refracted and polarised. It also shows the phenomenon of interference. (Young's double slit experiment) The above are the properties of waves. Light shows these properties and thus, this defines light as a wave.
Light's contribution to Science was when the scientists realised how fast light can travel around the world.
