What are the characteristics and properties of light?

Characteristics of light :—It moves in straight line called Rectilinear Propagation of light.It is stream of Corpuscles by Newton.It's Frequency unchanged when passed from one medium to other.It totally passed by transparent.It partially passed by Translucent.Properties of light :—Reflection of light: Every light follows the law of reflection which states that the angle of incidence is equal to the angle of reflection.Refraction of light: Refraction of light takes place when the light ray changes its velocity it passes from one medium to another.Dispersion: Dispersion of light is defined as the process in which the white light separates into different colours based on its wavelength when passed through a glass prism. Diffraction: The effect of bending light around small obstacle corners and hence its encroachment into the geometric shadow region is called diffraction.
