What is infrared led?
An IR LED is used in applcations like remote controls...it's much the same as as a normal Light Emitting Diode...Just that the wavelength of the emitted light is not present in the visible spectrum...
Why are waveguides used in high frequency?
I size of the object is comparable to wavelength, it will cause error. In high frequency wavelength is very low. So small-small objects will also cause interference, thereby increasing attenuation. Waveguides are hollow metals. Thus wave does not go out and stay inside. Metals does not cause any attenuation. Propagation of EM wave in waveguide is similar to light in optical fiber.
What is the descriptive use of an LED?
small, cost efficient light bulb.
What is the wavelength of 60 hertz?
60Hz has a wavelength of 5000 meters.
What is relation between wavelength and frequency?
wavenumber= 1/wavelength
What is wavelength of light emitting from LED?
It depends on the precise material used to make the LED. Different colors of LED emit different wavelengths.
What determines the frequency and wavelength of light emitted by an LED?
These are detemined by the band gap (a zone without electrons) of the solid used in LED.
What is the brightness and wavelength of the LED?
That depends on the LED in question
What is the function of led connectors?
Light emitting diodes or LED is used to save on electricity. LED connectors are a semiconductor device designed to produce a certain wavelength and type of light.
What is infared led?
Infared LED is a ~940nm Wavelength Lightbulb. The Light emmited is invisable to the human eye, but most cameras will be able to view the lightsource. Infared LED's are used Primarly in Remote Control Systems.
What do we use LED for now?
LED is a small type of light that is commonly used today.
If a wavehas a low speed but a higher frequency what can be said about its wavelength?
it has a small wavelength
High energey light has what wavelength?
High energy light has a small wavelength, and a high frequency.
Where do you find led lights?
You can find them in light bulbs, flashlights and other forms of illumination. If you are looking for LED light bulbs, CREE, PHILIPS, LITENZ are the companies that manufacture LED light bulbs using their own LEDs.
Is ultraviolet the shortest wavelength?
No. If the shortest wavelength is on the left end of the spectrum, the shortest wavelength is microwaves. if the shortest wavelength is on the right end of the spectrum, the shortest wavelength is gamma rays. I think it is microwaves because micro means small.
High energy waves have what size wavelength?
small
Why is LED used in place of a bulb in a tester?
we may use a LED in place of a bulb in a tester as LED glows even when there is a small electric current flow through it
