EM SPECTRUM Light & Color Wave Properties of Light Mirrors & Lenses Miscellaneous 1 1 1 1 1 2 2 2 2 2 3 3 3 3 3 4 4 4 4 4 5 5 5 5 5 These are tiny, particle –like bundles of energy that make up electromagnetic waves. These are tiny, particle –like bundles of energy that make up electromagnetic waves. Photons DAILY DOUBLE Put these in order of increasing energy: FM Radio Waves, Gamma rays, Infrared Light, Ultraviolet Light. DAILY DOUBLE order of increasing energy: FM Radio Waves, Infrared Light, Ultraviolet Light. Gamma rays, These waves have the highest energy of all electromagnetic waves. These waves have the highest energy of all electromagnetic waves. Gamma Rays This is the only part of the electromagnetic spectrum you can see. This is the only part of the electromagnetic spectrum you can see Optical Range (visible light) . Which travels faster, red light or blue light? Which travels faster, red light or blue light? Neither All EM Radiation travels at the same speed in similar media. These materials absorb or reflect all light, you cannot see through them. These materials absorb or reflect all light, you cannot see through them. Opaque Objects A green filter absorbs these colors of light A green filter absorbs these colors of light Red and Blue light are absorbed. Only Green is transmitted What color is formed when all three primary pigments are mixed? What color is formed when all three primary pigments are mixed? BLACK Red light and Green light combine to form yellow light so the light is (additive/subtractive) color. Red light and Green light combine to form yellow light so the light is additive color. This color of light has the shortest wave length and the highest energy. This color of light has the shortest wave length and the highest energy. VIOLET This is the word used to describe light that strikes an object. This is the word used to describe light that strikes an object. Incident Light This is the result of waves changing velocity when they travel from one medium to another. This is the result of waves changing velocity when they travel from one medium to another. Refraction This is what happens when waves are bent around a barrier. This is what happens when waves are bent around a barrier. Diffraction What type of interference is taking place as the crests combine to form new colors of light? What type of interference is taking place as the crests combine to form new colors of light? Constructive Interference Calculate the angle of reflection in the diagram. Angle of reflection is 30° Law of Reflection =’ This is the type of image produced by a plane mirror. (3 Characteristics) This is the type of image produced by a plane mirror. (3 Characteristics) A Virtual, Upright, True Size Image This is the name for the structure n the picture. Concave Mirror This type of image is produced when the light rays actually cross and touch the image. This type of image is produced when the light rays actually cross and touch the image. Real Image A convex mirror and a concave lens both produce this kind of image due to wave divergence. They both produce a Virtual, Upright, Smaller Image This is where the object must be placed to produce a real, inverted image with a convex lens.. This is where the object must be placed to produce a real, inverted image. Outside the focal point This scientist is credited with pioneering the study of light. This scientist is credited with pioneering the study of light. James C. Maxell Laser light is made up of this type of light to produce a concentrated beam. Laser light is made up of this type of light to produce a concentrated beam. Coherent Light Light travels fastest in this medium. Light travels fastest in this medium. A vacuum This type of filter only lets light of one orientation pass through. This type of filter only lets light of one orientation pass through. Polarizing Filter This technology uses the principal of Total Internal Reflection to transmit messages with light. This technology uses the principal of Total Internal Reflection to transmit messages with light. Fiber Optics
