Interaction of lights with different materials

• Blocking - an object blocks the light from a source forming a shadow
• Absorption - when light is blocked the materials takes light,changing it into energy that heats the matter
• Reflection - when an object blocks light,some of parts of it bounce back from the object
• Optics - is the study of the refraction, reflection and transmission of light
• Branch of science us called optics
• the light that your eyes react to is named visible or white light
• Transmission - light passes through some materials
• Refraction - light bend as it passes through different materials
• Visible light - the light that is visible to the human eye
• Light - is propageted in space electromagnetic waves this is known as electromagnetic wave theory of light
• Transparent materials - all lights to pass through them clear plastic and glass windows are example of transparent objects
• Translucent materials - do not allow all the light to pass through them like stained glass
• Opaque materials - do not allow any light to pass through them like woods
