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 else can I help you with?
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.
What percents of xrays are produced in a photoelectric effect?
The amount of xrays produced in a photoelectric effect varies. . . . alot.
Electrons ejected in the photoelectric effect are called?
Photo electrons. So current due to these photo electrons is named as photo electric current.
Is it true in the phenomenon known as the photoelectric effect electric current will flow when light shines on certain substances?
Yes, in the photoelectric effect, when light shines on certain substances, electrons are ejected from the material, creating an electric current. This effect occurs when photons (light particles) transfer enough energy to electrons in the material to overcome the binding energy holding them in place.
Why alkali metals used in photoelectric effect?
Alkali metals are used in the photoelectric effect because they have low ionization energies, making it easier for photons to eject electrons from their surface. This makes them efficient materials for producing a photoelectric effect. Additionally, alkali metals have a clean surface that allows for reliable and consistent results in experiments.
What is the effect of intensity on photoelectric current?
Increasing the intensity of light in the photoelectric effect results in an increase in the number of photons, which can lead to a higher number of photoelectrons being ejected from the metal surface. This results in an increase in the photoelectric current.
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.
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.
What factor effects the intensity of light the color of light and the type of electromagnetic radiation that is given off by the electron?
Photoelectric effect
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.
