Photoelectric effect.===================================== This phenomenon was discovered by Albert Einstein, for which he received the Nobel Prize for Physics. The solar cells that we use today is a direct application of the photoelectric effect, as the special metal absorbs Sun's photons and gives off electron (and the flow of electrons generates an electric current).
What else can I help you with?
The energy caused by the flow of particles with negative electrical charges is called?
The energy caused by the flow of particles with negative electrical charges is called electric energy. It is the movement of electrons through a conductor that creates an electric current, which can be harnessed for various applications.
What is the condition that limits the flow of electrons in an electric circuit is called?
The condition that limits the flow of electrons in an electric circuit is called resistance. Resistance is measured in ohms and is caused by factors such as the material of the conductor, its length, and its cross-sectional area.
What is a rock caused by lightning contact with sand called?
A rock formed by lightning striking sand is called a fulgurite. Lightning's intense heat fuses the sand particles together, creating a tube-like structure known as a fulgurite.
The word for A hollow left on the surface of the moon caused by an object striking its surface?
Crater
How does the aurora borealis relate to the structure of an atom?
The aurora borealis is caused by charged particles from the sun interacting with gases in the Earth's atmosphere. This interaction energizes the gases, causing them to emit light. Similarly, the structure of an atom involves charged particles (protons, neutrons, electrons) interacting to create energy levels and emission of light when electrons move between these energy levels.
The emission of electrons in high-vacuum tubes is caused by?
The heating by the filament causes the electrons to "boil off". Edison noted this phenomena and it was later picked up by Fleming who used a "grid" which could control the flow of the electrons by introducting a repelling field between the Cathode (heated element that emitted the electrons) and the anode that attracted the free electrons, thus the "Fleming Valve" was invented (the vacuum tube.
What affect might be caused by electrons being loosely bound to atoms in a material?
1. Chemical bonding 2. Photo electric emission 3. Electric current flow 4. Radiation emission
What is the form of energy caused by moving electrons called?
The form of energy caused by moving electrons is called electrical energy. It is the energy that is generated, transmitted, transformed, and used to power electronic devices and systems.
The energy caused by the flow of particles with negative electrical charges is called?
The energy caused by the flow of particles with negative electrical charges is called electric energy. It is the movement of electrons through a conductor that creates an electric current, which can be harnessed for various applications.
What is an acoustic emission?
An acoustic emission is a physical vibration caused by sudden movement within a material subjected to physical stress.
Which scientists postulated that the sharp lines in the emission spectra of elements are caused by electrons moving from high energy levels to low energy levels?
Niels Bohr proposed this model in 1913. His model of the atom suggested that electrons occupy specific energy levels and emit or absorb energy in quanta when they move between these levels, corresponding to the sharp lines observed in the emission spectra of elements.
What kind of electricity is caused by a continuous flow of electrons?
what kind of electricity is caused by a continuous flow of electrons
What has caused all of the craters on the moons surface?
Space rocks (meteors) striking the surface.
What is the name for a depression in the moon caused by an object striking its surface?
They are referred to as impact craters.
What is the condition that limits the flow of electrons in an electric circuit is called?
The condition that limits the flow of electrons in an electric circuit is called resistance. Resistance is measured in ohms and is caused by factors such as the material of the conductor, its length, and its cross-sectional area.
The lines at the ultraviolet end of the hydrogen spectrum are known as the lyman series wich electron transitions within an atom are responsible for these lines?
The series of lines in an emission spectrum caused by electrons falling from energy level 2 or higher (n=2 or more) back down to energy level 1 (n=1) is called the Lyman series. These emission lines are in the ultra-violet region of the spectrum.
