No. One of the principles of Physics is that all electrons are identical, and you
can't tell any one electron apart from any other one.
Even their numbers don't change. The number of electrons that come out of the
light bulb is the same number that went in.
What does change on the way through is their energy. They go in with relatively
higher energy, fall through several volts to a level of lower energy, and everything
the electrons lost radiates out of the bulb in the form of electromagnetic energy ...
a lot of heat and a little bit of light.
Yes, light can pass through a potassium permanganate solution to some extent. However, the intensity of light passing through will depend on the concentration of the solution and its thickness. Potassium permanganate is a deep purple color and will absorb some of the light passing through it.
No, electrons moving through space are not called light. Light is electromagnetic radiation that is made up of photons, while electrons are negatively charged subatomic particles found in atoms. Moving electrons can produce light when they transition between energy levels in an atom, but they are not the same as light itself.
When an atom absorbs energy from passing electrons, the electrons may move to higher energy levels within the atom. This can lead to the atom becoming excited or even ionized. Eventually, the atom will release the stored energy in the form of light or heat to return to a more stable state.
I think you probably know that the flow of electrons causes the filament to heat up and glow when the electricity is switched on and you want to know the number of electrons in the electricity? Well, it doesn't work quite like that, the electrons are all in the electron shells of the tungsten atoms making up the filament and there are the same number of electrons in these shells (and thus he filament) whether the electricity is on or off. When electricity is on, the electrons (in the outer shells) hop from one atom to the next, no extra electrons get into the filament (electrons coming in at one end are balanced by electrons going out at the other end) While all atoms have electrons, not all elements have atoms with 'free' electrons to allow this hopping - these elements will not conduct electricity.
They absorb photons.
To calculate current passing through a light globe, you can use Ohm's Law: current (I) = voltage (V) / resistance (R). To calculate voltage across a light globe, you can rearrange Ohm's Law to solve for voltage: voltage (V) = current (I) * resistance (R). Just make sure you know the resistance of the light globe in ohms.
An increase in the current through a bulb will increase its light output because more current means more electrons passing through the filament, which generates more heat and light. Conversely, a decrease in current will result in lower light output as there are fewer electrons flowing through the filament to produce light.
Electricity is carried through a wire by the flow of electrons. When a voltage is applied across the wire, the electrons move in response to this, creating an electric current that can power devices or light bulbs.
A current is the flow of electric charge, which requires a potential difference (voltage) to drive it. In the case of a light bulb, the voltage from a source (such as a battery or outlet) is needed to create the electric field that allows the electrons to flow through the filament of the bulb, generating light and heat in the process. Without this applied voltage, there is no driving force to push the electrons through the circuit, so no current flows.
Light is said to be transmitting when it is passing through any matter i.e. not through a vacuum but through a gas, liquid or solid. Light waves move at their highest speed when passing through a vacuum and slow down when passing through matter due to their interaction with the electrons around atoms, molecules or crystal lattices. Optical fibres made of special types of glass are used to transmit light signals in a similar way to copper wires used to transmit electrical signals.
The condenser adjusts the amount of light passing through the specimen.
I=v/r =110/121 =0.909A
In a simple circuit, energy is transferred from the power source (e.g., battery) to the components (e.g., light bulb) through the flow of electrons. The power source provides the electrical potential (voltage) that pushes the electrons through the circuit. As the electrons move through the components, they transfer their energy, causing the components to do work (e.g., produce light or heat).
Transmission
The amount of light passing through that's reaching your eye or the amount of electrons being absorbed. Depends on the microscope.
the bending of light when passing through an object
The splitting of white light into its component colors when passing through a glass prism is called dispersion.
