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!

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?
- select the adequate material for this experiment - switch to a light source with a shorter wavelength - switch to a light source with a higher intensity
Electrons ejected in the photoelectric effect are called?
Photo electrons. So current due to these photo electrons is named as photo electric current.
What percents of xrays are produced in a photoelectric effect?
The amount of xrays produced in a photoelectric effect varies. . . . alot.
The emission of electrons from metal caused by light striking the metal is called?
Photoelectric effect.===================================== This phenomenon was discovered by Albert Einstein, for which he received the Nobel Prize for Physics. The solar cells that we use today is a direct application of the photoelectric effect, as the special metal absorbs Sun's photons and gives off electron (and the flow of electrons generates an electric current).
Is it true in the phenomenon known as the photoelectric effect electric current will flow when light shines on certain substances?
Yes, it is true. See the link bellow.
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.
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 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.
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
Which phenomenon demonstrates a particle nature of light?
The particle nature of light is illustrated by the photoelectric effect.
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?
- select the adequate material for this experiment - switch to a light source with a shorter wavelength - switch to a light source with a higher intensity
Match the experimental conditions applied to the photoelectric effect observed.?
conditions of photoelectric effect
Which of the following modern technologies makes use of the photoelectric effect?
The photo-cell is the most practical example of the photoelectric effect. Light strikes a cathode, which causes an emission of electrons and produces current.
Electrons ejected in the photoelectric effect are called?
Photo electrons. So current due to these photo electrons is named as photo electric current.
What is the inverse process of photoelectric effect?
I think X-rays are the reverse process of photoelectric effect.
Is there any importance in photoelectric effect?
One of the most revolutionary concepts in physics is the photoelectric effect. The photoelectric effect occurs when radiant energy is impinged on various metals and electrons are ejected from the metal surface. The ejected photoelectrons have a certain kinetic energy which can be measured by the produced voltage. Photoelectric current cannot be explained by the wave theory as diffraction and interference can, however. The photoelectric effect is important because it revealed some of the limitations of the classical wave theory and it gave closer insight into the nature of light- namely the quantization as photons.
