what is light theory ?
Our modern understanding of light and color begins with Isaac Newton (1642-1726) and a series of experiments that he publishes in 1672. He is the first to understand the rainbow — he refracts white light with a prism, resolving it into its component colors: red, orange, yellow, green, blue and violet.
Light travels in a straight line, and therefore it was only natural for Newton to think of it as extremely small particles that are emitted by a light source and reflected by objects. The theory, however, cannot explain wave-like light phenomena such as diffraction and interference.

- light is a form of energy which our sense of sight that we can detect. it is made of electro-magnetic radiation and travels in the straight path
- the speed of light is which speed it travels
- light will travel in a completely straight line until it hit an object
White light is an equal combination of all the wavelengths in the visible light spectrum (red, orange, yellow, green, blue, indigo and violet) shown at the same intencity.
