Revision for Unit 5 Optics Definitions 1. Absorb: Is the process where light energy is taken in the object and converted to thermal energy. 2. Transmit: Is the process where light rays (or energy) go through the object and out of the other side. 3. Reflection: Is the process in which light strikes a surface and bounces back off that surface. 4. Opaque: Particles of an opaque material do not let any light to pass through; all the light energy is either absorbed or reflected. 5. Transparency: Is a measure of how much light can pass through a material. 6. Transparent: Particles in transparent material let light go through easily. 7. Translucent: Pars in translucent material transmit light but also reflect some, so a clear…show more content…
1. Light can transmit through some matter When encountering matter, light is often absorbed and/or reflected. However, it can also pass through some kinds of matter, depending on an object’s nature. 2. Light travels in straight lines When an object is held between a point source of light and a screen, a shadow is formed. If a line is drawn (representing a light ray) joining the light source, the top of the object, and the top of the shadow, this line is straight. 3. Light can be reflected When light strikes a surface, it can bounces back off that surface, Practically every surface reflects some light – if not, we would not be able to see colors. 4. Light can be refracted Light rays do not just change direction when they strike a reflective surface. They also change direction when they pass from one medium to another. 5. Light is absorbed 6. Light is a form of energy 5- Name the different forms of electromagnetic radiation from the longest wavelength to the shortest. 6- Name visible light’s spectral colors from longest wavelength to shortest
