Light

Light is a form of electromagnetic radiation that is visible to the human eye. It is a type of energy that can travel through a vacuum. Light behaves both as a wave and as a particle, known as photons.

Properties of Light

1. Reflection: The bouncing back of light when it hits a surface.
2. Refraction: The bending of light as it passes from one medium to another.
3. Dispersion: The separation of light into its different colors, as in a rainbow.
4. Diffraction: The bending of light waves around obstacles and the spreading of light as it passes through a narrow opening.
5. Polarization: The orientation of light waves in a specific direction.

Light Sources

Light can come from various sources, including:

• Natural sources such as the sun, stars, and fire.
• Artificial sources such as light bulbs, LED lights, and lasers.
