The amount of scattering that takes place depends on the wavelength of the light and the size and structure of the object. The sky appears blue because of this scattering behavior. Light at shorter wavelengths—blue and violet—is … See more Reflection is when incident light (incoming light) hits an object and bounces off. Very smooth surfaces such as mirrors reflect almost all incident … See more Absorption occurs when photons from incident light hit atoms and molecules and cause them to vibrate. The more an object's molecules move and vibrate, the hotter it becomes. This heat is then emitted from the … See more Refraction is when light waves change direction as they pass from one medium to another. Light travels slower in air than in a vacuum, and even slower in water. As light travels into a different medium, the change in speed … See more Diffraction is the bending and spreading of waves around an obstacle.
