Now assume you have super powers that use light What is something you could do? How would you behave if you used your super powers? What rules would you follow? Borsalino Kizaru

Properties of light Light travels in straight beams Light can be reflected Light can bend

Light and distance As light travels it dissipates into surroundings Closer an object is to the source of light the more light rays hit the object Closer = Brighter

Law of reflection The angle of reflection equals the angle of incidence

Law of reflection A ray of light will reflect off a plane mirror at the exact same angle as the incoming angle Incident ray = going in reflected ray = coming out

Types of reflection Regular: Smooth surface, Light is reflected evenly from the surface at the same angle they came in Diffuse: Uneven surface Rays are then reflected at different angles

Imagine: Light must conform as a unit Following a marching band director, and one person in the line goes into a thick mud puddle. As the person gets stuck and slows down the rest of the band line. To keep in uniform the band compensates and slowly bends to fit the angle of that person stuck in the mud until all are in the mud.

Light traveling through a prism Write what you think will happen when light hits the solid: Refracted light hits a more dense object, causing the light to refract and bend This bend separates the colors in white light and make a rainbow
