Ray optics - Study guides, Class notes & Summaries

The range of wavelengths in the visible spectrum is: a) 100 to 400 nanometers b) 400 to 800 nanometers c) 450 to 650 nanometers d) 400 to 800 meters (m) - ANS b) Depending on which reference is consulted, visible light is in the range of 400 to 800 nanometers. (Be sure to watch the units of measurement given in an answer. "Meters" in answer d should have indicated that it was incorrect.) Immediately on either side of the visible spectrum are the invisible light segments of: a)...

Chapter 3: Conducted and Wireless Media TRUE/FALSE 1. Category 1 twisted pair wire is not recommended for transmitting megabits of computer data. ANS: T PTS: 1 REF: 63 2. Category 1 wire is susceptible to experiencing noise and signal attenuation. ANS: T PTS: 1 REF: 63 3. Category 1 twisted pair wire produces less noise and signal attenuation than Category 2. ANS: F PTS: 1 REF: 63 4. Much of the Category 3 wire sold today is used for new computer network installations. ANS: F PTS: 1 REF: 6...

Isaac Newton said:Light moves as tiny particles Huygens said:Light is a wave Ray Model of LightLight is represented as a ray (arrow) which travels in a straight line. The ray model was introduced as a way to study how light interacts with matter, regardless of whether light is a particle or a wave. Ray optics or geometric optics. Sources of LightLuminous source (sun) produces own light. Illuminated source (moon) reflects light. OpaqueDoes not allow light to pass through TranslucentLight...
