How does light determine an objects's color?
Light determine an object's by the wavelength of light that reach to your eyes.light can reach your eyes after being reflected by an object,transmitted through an object,or emitted by an object.When your eyes receive the light,they send signals to your brain.Your brain interprets the signals as colors.
Can light waves carry sound?
By modulating the light you can send signals, they would need to be electronically translated to be heard as sound.
What are examples of electromagnetic radiation?
Examples of electromagnetic radiation include: Ultra-violet radiation red light Infra-red radiation blue light radar waves X-rays Television signals GPS signals green light cell-phone signals Microwaves AM radio waves Gamma rays 3G and 4G data links FM radio waves
What are optical sensors used for?
Optical sensors convert light, or changes in light, into electrical signals. They are used in products such as automatic lighting and flashes for cameras.
How is wind energy converted into light energy?
Wind power turns a turbine generator to produce electricity. Light is a form of electricity and electricity can be converted to light by light bulbs and fluorescent lighting, andd radio signals.
What is signal bandwidth?
Every line has an upper limit and a lower limit on the frequency of signals it can carry. This limited range is called the bandwidth. The signals ranging within the upper limit & lower limit are called bandwidth signals.
What is an add-drop mux?
An add-drop multiplexer also has the capability to add one or more lower-bandwidth signals to an existing high-bandwidth data stream, and at the same time can extract or drop other low-bandwidth signals, removing them from the stream and redirecting them to some other network path. An add-drop multiplexer also has the capability to add one or more lower-bandwidth signals to an existing high-bandwidth data stream, and at the same time can extract or drop other low-bandwidth signals, removing them from the stream and redirecting them to some other network path.
Why do complex non-sinusoidal signals produce greater bandwidth?
because they have more harmonics
How does cable modem internet access relate to bandwidth?
To access the internet via broadband cable, you will need a cable modem. Bandwidth is used for transmitting the signals of the internet to and from your home, and the cable modem is in place to allow the signals to be sent and received.
What is visible light frequency bandwidth?
Bandwidth of the visible light portion of the Electromagnetic Spectrum is approximately 384 Tera Hertz.
What is the role of multiplexers in signal transmission?
A multiplexor is used to encode multiple input signals for transmission over a single channel. This works because the bandwidth of the output channel is higher than the bandwidth of the input signals, allowing the input signals to share the output channel. At the other end, a de-multiplexor decodes the channel and decodes the individual input signals.
What is the difference between bandwidth and bit-rate in web steaming?
Bandwidth:- It is one characteristics that measures network performance is bandwidth. Bandwidth can be measured in two values:- 1. IN HERTZ 2. IN BITS/SEC. Bit Rate:- It is used to describes digital signals. the bit rate is the no of bits sent in 1s
If data signal is narrowband compared to the spreading signal, the resulting product of both the signals will have what bandwidth of spreading signal?
.
What signals does Ions charged particles form?
light signals
What signals a seed to awake?
The signals is the duration, intensity of light or the temperature
Why do most networks transmit digital rather than analog signals?
Digital signals are capable of carrying more information than analogue signals because digital signals make use of the bandwidth more efficiently by closely approximating the original analogue..
What is max speed at which data can be transmitted?
Data transfer rate (also called bandwidth)
