To convert light signals into digitally formatted electrical signals requires a device called a camera.
Also, an optical fiber digital converter in the course of fiber optics. For electrical power transmission, photovoltaic cells convert light into power.

∙ 10y agoThere are actually many ways to convert light into electricity:
One example is the CdS (Cadmium Sulfide) cell, a device that converts light into electrical "resistance". This device is a special type of "Resistor" that resists the flow of electrical current by an amount (mostly) proportional to the amount of light hitting it.
Another device is called an Optical Transducer, which is actually a class of "semiconductor" electronic devices that, somewhat similarly to the CdS cell, control the flow of electrical current based on the amount of light hitting it. Two important devices in this class are the "photodiode" and "phototransistor".
In each of the devices mentioned, the process of "converting" light into electronic signals is very different, and involves a pretty complicated area of physics known as "quantum mechanics", which deals with the behavior of matter (physical "stuff") and energy on the smallest scale: smaller than an atom, a scale called "sub-atomic".
It's an area of physics near and dear to my heart, and I recommend reading about it as much as you can.

What OSI layer converts the ones and zeros to electrical signals and places these signals on the cable?
physical layer
How are analog signals transmitted-?
Analog signals are transmitted as electrical waves.
What converts digital signals to analog signals and vice versa?
Digital signal is moreefficientimmune to noiseerror freethan analog signal.
What is the purpose of a digital converter?
A digital converter converts the analog signals that are received by your TV to digital signals. Most TV providers only offer digital TV these days, so you only need it if you're still using analog.
What is the difference between transistor and transformer?
A transistor in the right circuit, contributes a POWER GAIN by taking energy from an external power supply. A transformer actually has losses but is primarily used for Impedance Matching. This is very useful in establishing the most efficient arrangements for transmitting power from the source to the load. Impedance matching is an important function of all power transfer systems.
What piece of station equipment converts electrical signals to sound waves?
a speaker's 'coil' (and magnet) converts electrical signals to sound
What is a microphone?
a transducer that converts sound to electrical signals
What is a device that captures electrical signals and converts them to sound?
speaker
What is a inductive transducer?
it converts linier motion to electrical signals
For radio broadcasts sound signals are converted to?
For radio broadcasting, sound waves are converted to electrical waves that are further transmitted. This transformation is done by a device called a transducer, which converts physical parameters into an electrical form (signals).
What OSI layer converts the ones and zeros to electrical signals and places these signals on the cable?
physical layer
What instrument converts electrical energy to sound or image signals in a radio or television?
Loudspeakers and earphones convert electrical energy to sound energy. LCD monitors, plasma screens, and CRTs make images out of electrical signals.
Does the Network layer convert data packets from the Data Link Layer into electrical signals?
NO,IT CONVERTS them into frame
How is data retrieved from the telephone?
how is data retrieved from the telephone? the transmitter converts the sound waves to electrical signals which are sent through the telephone network to the receiving phone. the receiving telephone converts the signals into audible sound in the receiver.
What does the software IP Converter do?
IP Converter is a piece of software that converts electrical signals into pneumatic pressure. The electrical current is usually controlled by a microprocessor.
How was Alexander Graham Bell's telephone is related to electricity or magnetism?
Telephones converts sound into electrical signals, and backwards. Speakers with dynamic-coil transdusers convert electrical signals into sound by using the properties of electromagnetism.
What is hearing?
Your eardrums take fluctuations of the air pressure on your ears and converts them to electrical pulses, which are sent to the brain. The brain then interprets the electrical signals as different sounds.
