What is the effect of intensity on photo electric current?
Increasing the intensity of light incident on a photoelectric material increases the number of photons hitting the material, which in turn increases the rate at which electrons are ejected from the material (photoelectric current). Consequently, higher light intensity leads to a higher photoelectric current.
On what factors does photoelectric current depends?
The photoelectric current depends on the intensity of light shining on the surface, the frequency of the light, the type of material the surface is made of, and the energy of the individual photons. Increasing any of these factors can result in a higher photoelectric current.
How does the light intensity affect the photoelectric current?
Increasing light intensity results in more photons being incident on the photoelectric material, leading to more electrons being ejected, thus increasing the photoelectric current.
What type of energy uses the photoelectric effect?
Solar energy uses the photoelectric effect to convert light energy into electrical energy. When sunlight shines on a solar panel, the photoelectric effect causes electrons to be released, creating an electric current.
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 does the slope of the graph of photoelectric current versus intensity signify in the photoelectric effect?
The current rises as does the intensity of light detected. The more light the greater the intensity, and the greater the current. The answer to the question is that photoelectric current displayed on a graph is shown as a slope that varies with the intensity of light. Someimes it can go up, sometimes it can go down.The ultimate answer is that the photoelectric effect is unreliable, but it is improving!
What is the effect of intensity on photo electric current?
Increasing the intensity of light incident on a photoelectric material increases the number of photons hitting the material, which in turn increases the rate at which electrons are ejected from the material (photoelectric current). Consequently, higher light intensity leads to a higher photoelectric current.
Effect of intensity?
The photoelectric current is directly proportional to intensity.It also depends upon frequency, but frequency more than "THRESHOLD FREQUENCY" does not effect the current.The no. of electrons emitted per second by a photo-sensitive surface is directly proportional to the intensity of the incident radiations.So,the photoelectric current depends upon the intensity of the incident radiations.
On what factors does photoelectric current depends?
The photoelectric current depends on the intensity of light shining on the surface, the frequency of the light, the type of material the surface is made of, and the energy of the individual photons. Increasing any of these factors can result in a higher photoelectric current.
How does the light intensity affect the photoelectric current?
Increasing light intensity results in more photons being incident on the photoelectric material, leading to more electrons being ejected, thus increasing the photoelectric current.
If you are running a photoelectric effect experiment which adjustment might cause more current to flow?
Switching to a brighter light source. Switch to a light source with a higher intensity.
What is the relationship between the kinetic energy of ejected electrons and the intensity of incident light in the photoelectric effect?
In the photoelectric effect, the kinetic energy of ejected electrons is directly proportional to the intensity of the incident light. This means that higher intensity light results in higher kinetic energy of the ejected electrons.
If you are running a photoelectric effect experiment and your light source cannot create an electric current which adjustment might cause an electric current to flow?
Increasing the intensity of light or using a shorter wavelength light source can cause an electric current to flow in a photoelectric effect experiment. The energy of the photons should be increased to overcome the work function of the metal surface, allowing electrons to be ejected and generate a current.
If you are running a photoelectric effect experiment and you have a current flowing what would increase the flow?
The more intense the light, the greater the generated current will be. The important thing to understand about the photoelectric effect is that turning up the intensity of the light does not result in the electrons delivering more energy. Rather, a larger number of electrons are given the specific amount of energy that corresponds to the color of the light.
What type of energy uses the photoelectric effect?
Solar energy uses the photoelectric effect to convert light energy into electrical energy. When sunlight shines on a solar panel, the photoelectric effect causes electrons to be released, creating an electric current.
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.
Why does classical physics fail to explain the photoelectric effect?
Classical physics fails to explain the photoelectric effect because it is based on the wave theory of light, which predicts that the energy of a wave is proportional to its intensity. However, the photoelectric effect shows that the energy of ejected electrons is dependent on the frequency of light, not its intensity, as predicted by quantum theory.
