Light gates are simple optical circuits that have an opening between an emitter and receiver. If the path between the two is interrupted, a signal is sent to a computer or other data recorder. Some gates work in continuous mode, meaning the signal is different when the light is blocked, for example high or low voltage. Others work in pulsed mode, which responds by giving a pulse whenever the 'state' of on or off changes. And a third kind send a signal continuously while the path is open, and simply stop the signal when the path is broken.
These gates are typically used for timing and detection. Many automatic garage doors use a light gate to detect whether the door will come down on something (or someone!).
What else can I help you with?
How could you use a light gate to work out the speed of an object one point in time?
To calculate the speed of an object using a light gate, you would measure the time it takes for the object to pass through the gate. By dividing the distance between the light gate and the point where the object is launched by the time taken, you can determine the speed of the object at that point in time.
Define universal gate?
A universal gate is a logic gate that can be used to implement any logic function. The NAND gate and NOR gate are examples of universal gates because any other logic gate can be constructed using only NAND or only NOR gates.
When passing through a lock what color light?

What kind of simple machine is a garage gate?
A garage gate is typically considered a type of lever, as it uses a pivot point (fulcrum) and force (usually a motor) to lift the gate open and close.

IT'S THE ALARM LIGHT.
Should you use a stopwatch or light gate?
A stopwatch is more versatile as it can be used in a variety of situations, while a light gate is more specific and limited to measuring the time it takes for an object to pass through a light beam. The choice between the two depends on the specific requirements of your experiment or measurement.
How do I access my brake lights on my 1998 Chevy S-10?
