What happens when electrons travel through a filament?
When electrons travel through a filament, they collide with atoms in the filament material. These collisions cause the electrons to lose energy and heat up the filament, which then emits light. This process is how an incandescent light bulb produces light.
When electromagnetic radiation above the threshold frequency falls on an object it emits electrons?
Hhn
How does the substance inside a fluorescent tube change with an electrical charge?
the electrical charge excites the atoms and creates a plasma state that emits light
What happens to a radioactive nucleus when it emits alpha particle and What happens to a radioactive nucleus when it emits alpha particle?
When a radioactive nucleus emits an alpha particle, it decreases by two protons and two neutrons. This results in a new nucleus with a lower atomic number by 2 and lower mass number by 4. The emitted alpha particle is a helium nucleus (2 protons and 2 neutrons) and carries a positive charge.
When the electron emits lights does the electron move up to a higher energy level or down to a lower energy level?
In the Bohr model of the atom, an electron emits a photon when it moves from a higher energy level to a lower energy level.
What happens when electrons travel through a filament?
When electrons travel through a filament, they collide with atoms in the filament material. These collisions cause the electrons to lose energy and heat up the filament, which then emits light. This process is how an incandescent light bulb produces light.
Can atoms change energy levels?
Yes, atoms can change energy levels by absorbing or emitting energy in the form of light or heat. This process is known as electronic transitions. When an atom absorbs energy, its electrons move to higher energy levels, and when it emits energy, its electrons move to lower energy levels.
Conductor in a battery that collects or emits electrons?
zinc
Conducor in a battery that collects or emits electrons?
In a battery, or voltaic pile, the negative terminal or wire, called the anode, emits electrons in an electrical circuit. The other terminal, called the cathode, collects electrons in an electrical circuit.
What is the conductor in a battery that collects or emits electrons called?
Zinc
Where do initaitory electrons originate from in a gas discharge?
the gas is ionized, and free electrons, accelerated by the electrical field in the tube, collide with gas and metal atoms. Some electrons circling around the gas and metal atoms are excited by these collisions, bringing them to a higher energy state. When the electron falls back to its original state, it emits a photon, resulting in visible light or ultraviolet radiation.
Why does hydrogen emit different wavelengths of light than mercury?
Hydrogen emits different wavelengths of light than mercury because each element has a unique arrangement of electrons in its atoms. When electrons in hydrogen atoms move between energy levels, they emit specific wavelengths of light. In contrast, mercury atoms have different electron configurations, leading to the emission of different wavelengths of light.
What emits electrons in specific charge of electron experiment?
hot filament
Difference between direct and indirect cathode ray?
In a directly heated cathode, the filament is the cathode and emits the electrons. In an indirectly heated cathode, the filament or heater heats a separate metal cathode electrode which emits the electrons.
When electromagnetic radiation above the threshold frequency falls on an object it emits electrons?
Hhn
When light is incident on a metal surface it emits electrons What happens if the intensity of light increases?
If the intensity of light increases, more photons will be incident on the metal surface, leading to a higher rate of electron emission through the photoelectric effect. This results in a higher current of emitted electrons.
Why does sodium make fire yellow?
Energy from the fire temporarily promotes some of the electrons in atoms to higher energy levels. When they fall back down to the ground state, and this emits light of characteristic frequencies ... in the case of sodium, two of the most prominent lines are in the yellow-orange region of the spectrum.
