What occurs when light strikes a metal and electrons are released?
When light strikes a metal, it transfers energy to the electrons in the metal, causing them to be ejected in a process known as photoelectric effect. These ejected electrons are called photoelectrons and can be used in applications such as photovoltaic cells and photoemission spectroscopy. The energy of the ejected electrons is proportional to the frequency of the incident light.
What happens to electrons in the photo electric effect?
Electrons are ejected from a metal surface when it is exposed to light of sufficient energy. This phenomenon is known as the photoelectric effect. The energy of the incident light is absorbed by the electrons, causing them to be emitted from the metal surface.
Photoelectric affect what happens when light hits the metal?
When light hits a metal surface in the photoelectric effect, electrons are ejected from the metal if the light has sufficient energy (above the threshold frequency). This process demonstrates that light behaves as a particle (photons) with discrete energy levels when interacting with matter.
What happens to photons and photoelectrons when you double the amount of light shining on the metal?
If you double the amount of light shining on a metal, you will increase the number of photons hitting the metal surface. This can lead to more photoelectrons being ejected from the metal due to the increased energy provided by the additional photons.
How does the intensity of light affect the electrons emitted from a metal?
Increasing the intensity of light results in more photons hitting the metal surface, which can increase the number of electrons emitted through the photoelectric effect. This can lead to a higher current of ejected electrons being generated.

When a clean surface of potassium metal is exposed to blue light electrons are emitted if the intensity of the blue light is increased what will also increase?
i have the same question on my test haha for me, the answers are: a) The number of electrons ejected per second b) the maximum kinetic energy of the ejected electrons c) the threshold frequency of the ejected electrons d) the time lag between the absorption of blue light and the start of emission of the electrons e) none of these A the number of electrons ejected per second,,,,, correct answer

How does the mineral beryllium reflect light?
Beryllium is a metal that has a high reflectivity for visible light. When light strikes the surface of beryllium, it reflects off the metal's smooth surface, giving it a shiny appearance. This high reflectivity makes beryllium useful in applications where a highly reflective surface is desired, such as in optical systems or mirrors.
Will indium display the photoelectric effect with UV light?
Yes, indium can display the photoelectric effect when exposed to UV light. When UV light shines on a metal surface like indium, electrons are ejected from the surface due to the photon energy exceeding the work function of the metal. This phenomenon is known as the photoelectric effect.
How does the intensity of light affect the electrons emitted from a metal?
Increasing the intensity of light results in more photons hitting the metal surface, which can increase the number of electrons emitted through the photoelectric effect. This can lead to a higher current of ejected electrons being generated.
What is the equation for the work function of metals and how does it relate to the emission of electrons from a metal surface?
The equation for the work function of metals is given by the formula: Work Function Planck's constant x Frequency of incident light. The work function represents the minimum amount of energy needed to remove an electron from the surface of a metal. When light with a frequency higher than the work function strikes the metal surface, it can transfer enough energy to the electrons, causing them to be emitted from the metal surface.
What is the effect of frequency of incident light on photoelectric current?
The photoelectric effect is based on two principles. 1. The intensity or brightness of the visible light (number of photons): The higher the intensity (larger number of photons) determines the number of electrons that are released from the surface material. 2. The frequency of visible light (wavelength): The higher the frequency a beam of light has when it strikes the surface determines the speed (kinetic energy) of the electrons that are ejected from the material. This is independent from light intensity. The higher the frequency of the light, the higher the energy of the electrons emitted, and thus, the higher the current of the circuit.
The photoelectric effect states that electrons are ejected from a piece of metal?
B: When you shine a particular color of light on it.
