What is the form of an electromagnetic signal that is sent in a particular direction?
An electromagnetic wave is a signal that goes in all directions. The wave will move uniformly through its medium if the medium is uniform. A plane wave is the concept of think an electromagnetic wave only flows in one direction.
Is A microwave signal is sent through space in the form of optical waves?
Microwave signals are being sent through space through electromagnetic waves and not through optical waves. This type of signal is being used mainly in communications because of its narrower beams compared to other signals.
Is a microphone a input device?
Yes a microphone is an input device. Input/output devices are determined by the direction of the signal being transfered. If the signal is being sent to the Case (main part of the computer that does all the work) then the device is classified as an input device and vice versa. Since the signal from the microphone is sent to the Case, the microphone is "inputting" information into the computer.
How does a vehicle speed sensor work?
A gear inside the transmission turns a gear on the speed sensor. This creats a wave signal which is sent to the speedometer. The speedometer translates the signal and moves the needle in relation to the sent signal from the sensor. The signal is also sent to the ecu.
In a network that uses the star topology what is the signal that is sent to indicate a signal collision?
Jam signal
What is direct signal?
This is when the signal is sent directly to the organ, tissue, or a cell that needs it. An example of this is the neuron. A message is sent directly from or to brain
Can you use signal word in a sentence?
The crossing guard sent a signal to the children.
How does the overdrive button work on a dodge truck 1999?
When you push the button in, a signal is sent to the PCM to "block" overdrive.When you push the button in, a signal is sent to the PCM to "block" overdrive.
What time was tyhe first destess signal sent on titanic?
The first distress signal was sent out from Titanic at 12:27 AM ship's time.
What is a message sent by wire or radio?
A signal. It is a telegram.
How is trigonometry used in search and rescue missions?
Often the distressed people may not know their exact location. However, if two or more stations pick up their distress signals then each station can determine the direction from which the signal came. Trigonometric calculations can determine the exact location of the point from which the distress signal was sent and a S&R team is sent off to that location.
How do antennas work to receive and transmit signals?
Antennas work by converting electrical signals into electromagnetic waves for transmission, and vice versa for reception. When a signal is sent through the antenna, it creates an electromagnetic field that propagates through space. This field can be picked up by another antenna tuned to the same frequency, allowing for communication.
