16. A pair of red lights mounted 1 meter apart are far enough away that they are barely resolvable as two sources. A similar pair of blue lights (also 1 meter apart) is also mounted far enough away as to be barely resolvable. Which pair of sources is farthest from the observer

Taylor's experiment: 1. accurately measured the speed of light 2. locked together the phases of two light sources so that the interference pattern would not shift 3. showed that man's reaction time was much slower than the speed of light 4. showed that individual photons have wave characteristics

The metric unit of electrical power is the watt volt ampere ohm

The step-down transformer gives a current of 10a at 24v if the primary voltage is 240v calculate the 1_primary current 2_the power input 3_the power output
