A footcandle equals the illumination from one candle falling on a surface of 1 square foot at a distance of 1 foot. Define foot lambert - ✔✔A foot-lambert a unit of luminance = 1/π candela per square foot, or 3.426 candela per square meter (the corresponding SI unit). What does lux calculate? - ✔✔Lux calculates Footcandles 10.7 lux equals 1 footcandle What do nits calculate? - ✔✔nits calculates foot lamberts nit is the metric unit for screen or surface brightness What does PPE stand for ? - ✔✔Personal protective equipment What is the formula for aspect ratio? - ✔✔Ratio of image width to image height War HUH Aspect ratio of broadcast composite video systems? - ✔✔4:3 (also 1.33) four units wide by 3 high Aspect ratio of HD? - ✔✔16 units wide by 9 units high (16:9 or 1.78) One meter equals how many feet? - ✔✔1 m equals 3.28feet What is it called when we use mirrors to reflect light to a screen? - ✔✔Folding the light. This is done in an attempt to shorten the distance the light needs to be projected to be able to create a screen image. What is the pythagorean theorem? - ✔✔the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. What does ambient light affect for a projector or a monitor? - ✔✔contrast ratio What study would be conducted while checking for obstructions? - ✔✔A site line study What is the formula for ohms law? - ✔✔I=V/R I is the current through the conductor (amperes), V is the potential difference measured across the conductor (volts), and R is the resistance of the conductor (ohms). Ohm's law - ✔✔Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. where I is the current through the conductor in units of amperes, V is the potential difference measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. Ohm's law states that the R in this relation is constant, independent of the current.[3] 16:9 can also be written as? - ✔✔1.78 What would be the equation to calculate 16:9 to a decimal? - ✔✔Width divided by height What is 4:3 as a decimal - ✔✔1.33 What is throw distance? - ✔✔Length of projection beam necessary for a particular projector to produce an image of a specified size What should be done to get the full potential of a projector with a zoom? - ✔✔Put the projector in the middle of its zoom ratio What causes spherical aberration? - ✔✔Curvature of the lens on a projector What is a RFI? - ✔✔Request for information What is a RFQ? - ✔✔Request for qualifications What is a RFP? - ✔✔Request for proposal What is a RFC? - ✔✔Request for change What is a CO? - ✔✔Change Order What is a CCD? - ✔✔Construction change directive What are two types of bid processes? - ✔✔One envelope and a two envelope bid process What is generally in the first envelope in a two envelope bid process ? - ✔✔The RFP or request for proposal What is generally in the second envelope of a two envelope bid process ? - ✔✔The RFQ or request for qualifications What is the definition of a conventional bid process? - ✔✔negotiate price first When is Subsystem testing done? - ✔✔In the shop or prior to install When his system testing done? - ✔✔At the end of the project example: you can test the acoustic system in another room What is the last item in a sound system? - ✔✔The ears/the customer What are the three different types of screen information a presenter would use that would help you determine in image size ? - ✔✔"view-for general viewing, read-for detail viewing with clues, inspect-detail viewing without clues" What is the formula for general viewing ? - ✔✔This screen height times eight What is the formula for detailed viewing? - ✔✔This screen height times six What is the formula for inspection viewing? - ✔✔This screen height times four What is the formula for the nearest viewer? - ✔✔The nearest viewer can be no closer than 1X the image width What is the 150 rule? - ✔✔A rec [Show More]
