Scientists originally thought that the intensity of light would affect the number of electrons ejected, but not their energy. They believed that increasing the intensity would only result in more electrons being emitted from the surface, without impacting their kinetic energy.
What else can I help you with?
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.
Is photocurrent proportional to the intensity of light?
Yes, photocurrent is typically proportional to the intensity of light. Higher intensity light generates more electrons in the photoconductive material, leading to a higher current.
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 do scientist using classical Newtonian expect to observe during a photoelectric effect?
Scientists using classical Newtonian physics would expect to observe a gradual increase in the kinetic energy of emitted electrons when exposed to increasing light intensity in the photoelectric effect. They would also expect the emission of electrons to start immediately upon exposure to light, regardless of its frequency.
When light is incident on a metal surface it emits electrons What happens if the intensity of light increases?
If the intensity of light increases, more photons will be incident on the metal surface, leading to a higher rate of electron emission through the photoelectric effect. This results in a higher current of emitted electrons.
Scientists use fujita scale to measure hurricane intensity.?
scientists use fajita scale to measure hurricane 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.
Why do scientists measure light intensity?
to know how is the light heavy
Do scientists use the Fujita scale to measure hurricane intensity?
The Fujita scale is only for tornado intensity. Meteorologists use a different wind scale for hurricanes called the Saffir-Simpson scale.
Why is the symbol i for current?
because current was originally reffered to as electrical intensity.
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.
Is photocurrent proportional to the intensity of light?
Yes, photocurrent is typically proportional to the intensity of light. Higher intensity light generates more electrons in the photoconductive material, leading to a higher current.
Do Scientists use the Fujita to measure hurricane intensity?
No. The Fujita scale is used to rate the intensity of tornadoes. Hurricanes are rated on the Saffir-Simpson scale.
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
How many electrons are emitted when calcium is flashed with light of wavelength 340 nm and intensity of 50 percent?
The number of electrons emitted when calcium is flashed with light of a certain wavelength and intensity depends on the photoelectric effect, which is related to the energy of the photons hitting the metal. Without the energy of the photons and the work function of calcium, we cannot determine the number of electrons emitted.
Why people use I not A for amps?
It was originally used for "current" which is represented today in amps. It stood for the (intensity) of the current.
What do scientist using classical Newtonian expect to observe during a photoelectric effect?
Scientists using classical Newtonian physics would expect to observe a gradual increase in the kinetic energy of emitted electrons when exposed to increasing light intensity in the photoelectric effect. They would also expect the emission of electrons to start immediately upon exposure to light, regardless of its frequency.
