Question

Descibe the properties of light?

Answer 1

http://en.wikipedia.org/wiki/Light

Three primary properties of light are:

    * Intensity;

    * Frequency or wavelength and;

    * Polarization.

Answer 2

Visible light is just one particular type of electromagnetic radiation. Other types of electromagnetic radiation include radio waves, infrared radiation (heat), ultraviolet radiation, x-rays and gamma -rays. The different types of radiation are distinguished by their wavelength, or frequency.  

In the early 20th century, experiments revealed that there were some phenomena associated with light that could only be explained by a particle picture. Thus, light as it is now understood, has attributes of both particles and waves.

Light can be reflected (cause to return or rebound), refracted (alter by viewing through a medium), dispersed (to send off in various directions, like during fog), or interfered (the process in which two or more light, sound, or electromagnetic waves of the same frequency combine to reinforce or cancel each other, the amplitude of the resulting wave being equal to the sum of the amplitudes of the combining waves).
