Reflection
Light waves may also be reflected off a surface. Reflection of light generates an image but there must be a source of light for humans to see an object (Koch, 2013). In human vision, light that is reflected from an object is what ultimately helps produce an image. An item we see looks a certain color because the light is reflecting that color more than others. For example something that is red reflects red light while the other colors gets absorbed and the energy those specific rays are carrying are turned into energy (Kelleher, n.d.).
