The laser light is pulsed and shone onto a reflective surface. The returned reflection is picked up by a phototransistor.
The time taken for the pulse to be sent and returned, can be measured by electronics within the device.
The speed of light is 300,000 Km /sec, (186,000 miles/sec) which is very fast, but finite.
The timing circuits within the device have to be very accurate and stable. This is acheived by using crystal oscillators within the device, to act as timing comparison.
What else can I help you with?
Does electric work when power cord is not attached to device?
No, an electric device will not work if the power cord is not attached as it needs the electricity provided by the cord to function. Without the power cord, there is no source of electricity to power the device.
50 hz 60 hz 120 vac will work on 220 vac?
No, a device designed to work on 50 Hz/60 Hz at 120 VAC will not work on 220 VAC without a voltage converter or transformer. The difference in voltage can damage the device and may not function properly. Always ensure that the device is compatible with the voltage and frequency of the power supply before connecting it.
Predict whether a fuse will work successfully if it is connected in parallel with the device it is supposed to protect?
A fuse will not work successfully if it is connected in parallel with the device it is supposed to protect.First, it will blow because it has no resistance in series with it. Second, once it blows, the device still has power applied to it. Fuses must be wired in series.
Is electricity needed ta make an external antenna work?
No, an external antenna can work without electricity. It simply picks up radio frequency signals from the air and sends them to the device it is connected to. The device, such as a TV or radio, uses its own power to process and display the signals.
Will a 9 volt 800 milliamp adapter work with a 9 volt 400 milliamp device?
Yes, the 9 volt 800 milliamp adapter will work with the 9 volt 400 milliamp device. The device will only draw the amount of current it requires, so having a higher amperage rating on the adapter is fine. The voltage should match to ensure compatibility.
If a device does not work after the OS upgrade what can you do?
If the device does not work then you will have to update the firmware on the device
A heat engine is a device that converts work into heat?
No, a heat engine is not a device that converts work into heat. It is the opposite, which means it is a device that converts heat into work.
What is a device used to make work easier?
A device to make work easier is a machine, such as a lever.
Can blackberrys work with any sim card?
As long as it is a GSM device and not a Nextel iDEN device then it will work as long as the device has been unlocked.
What does an output device in an electrical circuit do?
how does input device work
How can you say that your eyes work like an input device?
How can you say that your eyes work like an input device?
Percentage of energy that is used by a device to perform work is called?
That is called the "efficiency" of the device.
WHAT THE ENGINE?
A mechanical device that can work by means of fuel consumption. A mechanical device that can work by means of fuel consumption.
Will a device designed for 110v work on 220v?
No, a device designed for 110v will not work on 220v without a voltage converter.
What device works as an output and input device?
A Touchscreen Monitor will work as an input and output device
They work with any computer that has a USB port, to a USB device.?
They work with any computer that has a USB port, to a USB device.
Can a device designed for 110v work on 220v?
No, a device designed for 110v cannot work on 220v without a voltage converter.
