Who concluded that particles can have some of the properties of light?
Albert Einstein concluded in his paper on the photoelectric effect that light behaves as particles. This led to the concept of photons, which are particles of light that have properties of both waves and particles.
What is another term used to describe the writing stage of the laser or LED printing process?
The writing stage of the laser or LED printing process is also known as the exposure stage. This is where the image or text to be printed is transferred onto the photosensitive drum using a laser or LED beam.
Which system shows a transformation from chemical to electrical and light energy?
A system that demonstrates a transformation from chemical to electrical and light energy is a battery-powered LED flashlight. The batteries store chemical energy, which is converted into electrical energy to power the LED light, producing light energy as a result.
What are the example of monochromatic source of light?
Examples of monochromatic sources of light include lasers, certain LED lights, and spectral lamps that emit light of a single specific wavelength or color. These sources produce light that is highly pure and composed of a single frequency.
Why was wave theory of light inadequate and was rejected?
In some experiments, light appeared to have wave properties, but in others, it appeared to have particle properties. The two ideas were believed to be in conflict - light was believed to be either one or the other. However, today it is accepted that light has both particle and wave properties.
What kind of electronic has two legs and gives out light?
An LED, laser, or light bulb.
What do the acronyms 'LASER' and 'LED' stand for?
LED is "light emitting diode". LASER was originally an acronymn which meant "Light Amplification by Stimulated Emission of Radiation". Easy to see why they'd want to shorten that one.
What are the two sources of light used in Fiber Optic Cables?
laser and led
Can you put a LED inside a laser housing to focus it into a beam just like a laser diode would?
No. Unless the LED is specifically a laser, you can not make it focus like a laser by putting it in a housing. A laser produces coherent light, which is why it acts like a beam. A normal LED is not coherent, and you can not make it so. Although you can not make a collimated incoherent light beam able to travel similar distances as a collimated laser beam, you can collimate incoherent light into a beam which would travel some distance with a small amount of divergence.
What is the red light of the mouse?
That would be the laser sensor of the mouse.Wireless mouse tend to have laser sensors and Optical the ones with cord. They utilizes light-emitting diodes (LED) or laser as a method of tracking movement.
Difference between light emitting diode and laser?
LEDs, known as light emitting diodes, are comprised of two lead semiconductor light sources. Laser transmitters, also known as laser diodes are comprised of an electrically charged semiconductor laser.
Where is the Hard Drive LED in a computer?
The LED is in the screen where the computer shows the light and displays on the computer when its on.
Electronic devices that begin with the letter L?
Laptop LED TV Landline phone Laser printer
What is the difference between PIN diode and Avalanche Photo diode?
ets see the comparison of LED Diode vs LASER Diode.LED Diode :-Full form of LED- light emitting diode.-LED's are small in size, longer life, reliable and require little power.-Here generation photon by spontaneous emittion.-LED's produce a divergent and incohrent light beam.-Types of LED 1> surface emitter and 2> Edge emitter.-Their response is fast.-A wide range of wavelengths is available.-The cost of LED would be less.-An intensity of generating light is less.-Coupling efficiency of LED with fiber is less.-LED's use with the multimode fibers.-Bandwidth of led is moderate.-In led have require no extra circuit because of its simple circuit.-Here require drive current is 50 to 100mA.LASER Diode :-Full form of LASER - light emplification by stimulated emmition of radiation.-Laser's are bigger in size, longer life, less reliable and require more power then LED.-Here generating photon by stimulated emittion.-Laser produce q monochromatic and coherent light beam.-Types of Laser 1> semiconductor laser and 2> Gas laser.-Their response is faster than LED.-A small range of wavelength is available.-The cost of Laser would be higher.-Coupling efficiency of Laser with fiber is higher.-Laser use with both single mode and multi mode fibers.-Bandwidth of laser is higher.-In laser have require extra circuit for isolation of temperature reaction.-Here require drive current is Therashold current 5 to 40mA.
What is the another name of laser printer?
Another name for a laser printer is an LED Printer. LED stands for Light Emitted Display. Laser Printers are more common in business than in the home, but they can work in either.
Why are LED lights so bright?
Its because, LED light is usually in a laser light. Lasers are ussually bright, very bright. thats all, i know might be a lie. might not--
What does it mean when led light stays on aftermarket alarm?
When the LED light on an aftermarket alarm stays on, it means that the alarm is active. The light generally shows that the alarm status is "ready."
