What colors of light would cause the photoelectric effect?

What colors of light would cause the photoelectric effect?

The photoelectric effect is the observation that under certain conditions, light striking a metal surface can cause electrons to be ejected. In the animation, the light increases in energy as it goes from red, to orange to yellow to green and then blue

Can visible light cause photoelectric effect?

The photoelectric effect is the process in which electromagnetic radiation such as visible light, x rays, or gamma rays strike matter and cause an electron to be ejected. The ejected electron is called a photoelectron.

Can white light be used for photoelectric effect?

White light is shined on a metal surface that exhibits the photoelectric effect according to the graph as shown for each component of white light.

What light causes the photoelectric effect?

ultraviolet light

Can red light cause photoelectric effect?

No, it is not possible but due to present technology it may be possible. Explanation: The energy required to rip an electron out of its orbital is equal to the electrons work function, and photons in red light lack this energy.

What type of light is most likely to produce photoelectrons?

Light amplitude was expected to be proportional to the light energy, so higher amplitude light was predicted to result in photoelectrons with more kinetic energy.

Will yellow light produce the photoelectric effect?

The wavelength of light is inversely related to its frequency. Because the wavelengths of yellow and red light are longer than those of green light, their frequencies are lower, and no photoelectrons are produced when yellow or red light strikes metal

Is visible light the only type of EM radiation that cause the photoelectric effect?

No. The photoelectric effect just requires that the incident photon energy be greater than the work function of the material.

Which rays can cause photoelectric effect?

Other photoelectric effects are caused by radiation at higher frequencies, such as X-rays and gamma rays. These higher-energy photons can even release electrons near the atomic nucleus, where they are tightly bound.

What causes the photoelectric effect?

The photoelectric effect occurs when light shines on a metal. Sometimes electrons are emitted. Predictions of the wave theory of light: Light of any frequency will cause electrons to be emitted.

Can we use any light for photoelectric effect?

The type of light that is needed to cause the photoelectric effect is any light that has enough energy (photon energy) to facilitate the ejection of electrons from a metal. In most cases, it is the ultraviolet light.

Which type of light is used in photoelectric effect?

ultraviolet light

Is red light is necessary for photoelectric effect?

No, it is not possible to see the photoelectric effect with red light. The energy necessary to rip an electron from its orbital is equal to the electrons work function, which red light photons lack.

Can white light cause photoelectric effect?

The photoelectric effect is the observation that under certain conditions, light striking a metal surface can cause electrons to be ejected. In the animation, the light increases in energy as it goes from red, to orange to yellow to green and then blue

Can photoelectric effect be seen with red light?

No, it is not possible but due to present technology it may be possible. Explanation: The energy required to rip an electron out of its orbital is equal to the electrons work function, and photons in red light lack this energy.

Why red light is used in photoelectric effect?

The photoelectric effect is the observation that under certain conditions, light striking a metal surface can cause electrons to be ejected. In the animation, the light increases in energy as it goes from red, to orange to yellow to green and then blue

Why does the photoelectric effect not work for red light?

Explanation: The photons in red light to not have the necessary energy required to rip an electron out of its orbital (this needed energy is equal to the electrons work function) due to the large wavelength and low energy of the red light. Was this answer helpful?

What type of light can produce photoelectric effect?

ultraviolet light

Are photoelectrons emitted from red light?

Red light does not eject photoelectrons (even if it is very bright). Green light does eject photoelectrons (even if it is very dim). Blue light ejects photoelectrons with more energy than green light (even if it is very dim).

Can white light produce photoelectric effect?

The photoelectric effect is the observation that under certain conditions, light striking a metal surface can cause electrons to be ejected. In the animation, the light increases in energy as it goes from red, to orange to yellow to green and then blue

What light will produce in the photoelectric effect?

The photoelectric effect is the observation that under certain conditions, light striking a metal surface can cause electrons to be ejected. In the animation, the light increases in energy as it goes from red, to orange to yellow to green and then blue

Will yellow light eject electrons?

The photoelectric effect was discovered in 1887 by the German physicist Heinrich Rudolf Hertz. In connection with work on radio waves, Hertz observed that, when ultraviolet light shines on two metal electrodes with a voltage applied across them, the light changes the voltage at which sparking takes place.

Is red color necessary for photoelectric effect?

Photoelectrons are emitted from a metals surface if the frequency of incident radiation is more than the threshold frequency of the given metal surface. As yellow light does not eject photoelectrons from a metal it means that the threshold frequency of the metal is more than the frequency of yellow light.

What type of radiation is used in photoelectric effect?

electromagnetic radiation

Is visible light is the only type of electromagnetic wave?

Visible light is a form of electromagnetic (EM) radiation, as are radio waves, infrared radiation, ultraviolet radiation, X-rays and microwaves. Generally, visible light is defined as the wavelengths that are visible to most human eyes.
