Light Definition and Examples

Light originates from a source, reflects off things that our eyes perceive, and is then processed by the brain to give us the ability to see. According to Maxwell, magnetic and electric fields move as waves that are traveling at the speed of light.

On Earth, the Sun is the primary source of natural light. Fire has historically played a significant role in human lighting, from primitive campfires to contemporary kerosene lamps. Electric lighting has effectively replaced firelight as a result of advancements in electric lights and power systems.

Properties of Light

Direction of propagation, Intensity, frequency and polarization make up the fundamental characteristics of light. One of the basic constants of nature is its speed in a vacuum, 299792458 m/s. Some of the properties of light are:

• Refraction
• Reflection
• Dispersion
• Interference
• Polarization
