what else can it be used to get light instead of LED in pump lines for rooters ?
Homework Answers
we can use cfl,halogen bulb in stead of led in pump lines for rooters.these two can be proved to posses better usability than led bulb in pump line dor rooters.

(about LED) In the case of light-emitting diodes that convert electrical signals into light, what properties of light can be used? wave or particle??? I know that its not corresponding to photoelectric effect. But Isn't the energy being released into the form of light a particle of light? i mean does light-emitting diodes use or can be explained by particle property of light???

1) Your company currently owns a used pump that has been damaged. A contractor has said that the pump could be repaired at a cost of $35,000, which would make the pump workable for the next five years. If you instead sell the damaged pump for scrap, you can get $5,000 for it. A brand-new pump would cost $80,000, and would last for seven years. If your company's minimum acceptable rate of return is 10% per year before taxes, which...

Diodes can emit light. a) In a light emitting diode, what must be done electrically to cause the diode to emit light? How is the light emitted? b) What feature of the band gap is needed to make the LED emit light without much energy going into heat? c) Is the light from an LED produced primarily by spontaneous emission or stimulated emission? d) What feature of the LED determines the color of the light? e) What addition to an...

5. A light emitting diode (LED) is a diode that lights up when a current flows across it. The symbol for an LED is shown below (sometimes wiggly arrows are used to represent the light instead.) For this question we will assume we are working with LEDs that have a turn-on voltage of VoN-1V and a reverse breakdown voltage of VBR-8V a. You hook up a single LED to a power supply that can put out vol tage from -10...

Light-emitting diode (LED) light bulbs have become required in recent years, but do they make financial sense? Suppose a typical 60-watt incandescent light bulb costs $.45 and lasts for 1,000 hours. A 7-watt LED, which provides the same light, costs $2.25 and lasts for 40,000 hours. A kilowatt-hour of electricity costs $.121, which is about the national average. A kilowatt-hour is 1,000 watts for 1 hour. However, electricity costs actually vary quite a bit depending on location and user type...
