What occurs when light strikes a metal and electrons are released?
The electrons in the electron sea absorb and re-emit the light.
When a source of dim orange light shines on a photosensitive metal no photoelectrons are ejected from its surface What could be done to increase the likelihood of producing photoelectrons?
increase the brightness of of the orange light source
What is the ability of light to eject an electron from a metal according to albert Einstein?
This is a phenomenon known as the photoelectric effect. Light arrives at the metal and gives energy to the electrons, causing them to be ejected from the metal.
In what way does the photoelectric effect support the particle theory of light?
In order for an electron to be ejected from a metal surface, the electron must be struck by a photon with at least the minimum energy needed to knock the electron loose.
Does light reflect off the surface of metal?
It reflects off the surface of shiny and smooth metals.

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

What happens when metal strikes a hard surface?
i thing it produces sound?
The photoelectric effect states that electrons are ejected from a piece of metal?
B: When you shine a particular color of light on it.
What kind of surface of a metal can light reflect off of?
A smooth shiny surface.
How does light interact with shiny metal?
It reflects the light, that is how the surface seems shiny.When light hits a shiny surface it is reflected and is sometimes bent.
What is a piece of rock or metal that falls through the atmosphere and falls to earth?
A meteorite is a piece of rock that strikes the earth's surface.
Does light reflect off the surface of metal?
It reflects off the surface of shiny and smooth metals.
Why the wave model for radiation does not account for the photoelectric effect?
Predictions of the wave model: Energy of light was dependent on the amplitude of the light wave, which was manifested as the brightness of the light. Higher amplitude (brighter) light would cause the ejected electrons to be more energetic. Colour of light was dependent on the frequency of the light but frequency had no bearing on the energy of the ejected photons. Predictions of the photon model: Both the energy of light and the colour of light was dependent on the frequency of the photons. Higher frequency would cause the the ejected electrons to be more energetic. The number of photons was manifested as the brightness of the light. Higher number of photons (brighter) light would cause the ejected electrons to be more numerous (higher current). Observations from the photoelectric effect experiment: Ejected electron energy was directly related to the frequency of the light and brighter light resulted in higher current. These observations were explained by the photon model and could not be explained with the wave model.
