WebReflection of light. Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular … WebThese colors are often observed as light passes through a triangular prism. Upon passage through the prism, the white light is separated into its component colors - red, orange, yellow, green, blue and violet. The …

"WebIn the visible spectrum, reflectivity increases with cloud optical depth, which is approximately proportional to liquid water path (vertically integrated liquid water) if the effective particle size remains constant. Therefore, clouds with higher values of liquid water path are more reflective. " - Reflected visible light
