Alkali metals are used in the photoelectric effect due to their low work function, which allows them to easily emit electrons when exposed to light. Their single valence electron is loosely bound to the nucleus, facilitating its ejection upon absorption of photons. This property makes alkali metals, such as cesium and potassium, highly effective in photoelectric applications, including photodetectors and solar cells. Additionally, their relatively high reactivity and availability make them suitable for various experimental setups.
What else can I help you with?
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 ability of light to cause electron movement and electric current?
The ability of light to cause electron movement and electric current is known as the photoelectric effect. When photons of light strike a material, they can transfer their energy to electrons, causing them to be ejected from the material, which can then result in the generation of an electric current.
What does photoelectric effect in plants refer to?
Photo relates to light. Of course light is electromagnetic wave. Electric relates to electron movement. So by making electromagnetic waves such gamma ray, X-ray, UV rays and even visible light we can eject electrons right from the surface of certain substances. This is termed as photo electric effect or emission.
What is the reverse process of photoelectric effect?
reverse process of photo electric effect is done by the supply of electrons or heat to the metal that radiate certain radiation. among them the metals which emit visible radiation are normally used in house hold appliances
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).
Are alkali metals suitable for photo electric emission?
yes alkali metals are suitable for photo electric emission
What alkali metal is using for photo cells?
Cesium
What happens to electrons in the photo electric effect?
Electrons are ejected from a metal surface when it is exposed to light of sufficient energy. This phenomenon is known as the photoelectric effect. The energy of the incident light is absorbed by the electrons, causing them to be emitted from the metal surface.
What are the proofs of the particles nature of light?
photo electric effect,compton's effect
What are the proofs of the particles of nature of light?
photo electric effect,compton's effect
Are all metals useful for photo electric effect?
The photoelectric effect can be demonstrated using any metal. But for some ofthem, you might have to come up with a source of inconveniently-high-energyE&M radiation in order to demonstrate it.
Electrons ejected in the photoelectric effect are called?
Photo electrons. So current due to these photo electrons is named as photo electric current.
For what topic did Albert Einstein win a Nobel Peace Prize?
it was for photo electric effect ~_~
Date Einstein won the nobel prize in physics?
1921 for his work on the photo electric effect
What famous prize did Albert Einstein win?
The Nobel Prize for his work on the photo-electric effect.
Albert Einstein got the Nobel Prize for his?
photo-electric effect, which is a very obvious manifestation
Who discover photo electric effect and what date?
The photo electric effect was explained by Einstein in 1905 when he theorized that light could transfer its energy like a particle and knock electrons out of metals. But the actual effect had been observed by a number of scientists since 1887, they just couldn't come up with a satisfactory theory that explained everything they observed. I believe he got the Nobel Prize for his photo electric effect theory, although he is more famous for his Relativity theories.
