Properties of Light
According to the observations light travels in dual nature i.e..,, wave nature and particle nature because of this dual nature it exhibits the following properties. They are
 * 1) Reflection 2. Refraction 3. Dispersion of light 4. Interference 5. Diffraction 6. Polarization 7. Light travels in vacuum 8. Speed of light is constant

Reflection:
It is a property of light when a light ray incidence on a reflecting surface by making an angle it comes back with the same angle is called reflection light. It is due to wave nature of light.

Examples for reflective surfaces are mirror, water.

Refraction:
The bending property of light when it travels from one medium to another medium is called refraction. It is due to the molecular interactions of the medium.

 Examples:  Usually it can be observed in case of air-water mediums

Dispersion of light:
The splitting of white light into its constituent colours by the particle nature is called dispersion of light.

 Examples:  By using this property prism splits the white into the VIBGYOR

Interference:
It is a property of light in which the superimposition of two same frequency or nearly same frequency containing waves to form a same higher or lower amplitude wave is called Interference of light. It is due to wave nature of light.

 Example:  Radio interferometry for measuring micro level distance, interferometer

Diffraction:
It is a property of light in which the changing of path by light when it strikes the obstacles is called diffraction

 Examples:  It can be observed in case of formation of shadows

Polarization:
It is the property of light in which the vibration of waves restricted to one plane.

 Example:  It can be used in 3D glass

Light travels in vaccum:
Due to the electromagnetic wave nature of light it travels even in vacuum also.

 Example:  because of this property the radiation of sun is reaching earth.

Speed of Light is constant:
Because of wave nature of light it travels with a constant speed in vacuum that is 3x108 m/s2.

 Example:  This is the property in which used to measure the astronomical distances by the name of Light years.
