What is another word for photoelectric effect?
the phenomenon in which the absorption of electromagnetic radiation, as light, of sufficiently high frequency by a surface, usually metallic, induces the emission of electrons from the surface. Also called photoemission.
What explained the photoelectric effect?
photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation. The effect is often defined as the ejection of electrons from a metal plate when light falls on it.
What is the difference between photoelectric effect?
The basic difference between the Compton effect and the photoelectric effect, the Compton effect occurs on the free electrons while the photoelectric effect occurs on the bound electrons. In photoelectric effect, the electrons absorb the energy of the photons.
What is the photoelectric effect and what did it prove?
The photoelectric effect proves that light has particle-like activity. The photoelectric effect happens when photons are shone on metal and electrons are ejected from the surface of that metal. The electrons that are ejected are determined by the wavelength of light which determines the energy of photons.
What is photoelectric effect class 11?
“The phenomenon of ejection of electrons from the surface of a metal when light of suitable frequency strikes on it, is called photoelectric effect. The emitted electrons are called photoelectrons.”
What is photoelectric effect PDF?
The phenomenon of emission of electrons from mainly metal surfaces exposed to light energy (X – rays, γ – rays, UV rays, Visible light and even Infra Red rays) of suitable frequency is known as photoelectric effect.
Which statement best describes the photoelectric effect?
The photoelectric effect is the emission of electrons from a metallic surface when there is a relatively high frequency of electromagnetic radiation on it. The smallest unit of light, with no mass and no electric charge, or any electromagnetic energy. Photons serve as ions as well as waves.
What do you mean by photoelectric effect class 12?
The phenomenon of emission of electrons from the surface of the metal when the light of suitable frequency falls on it is called the photoelectric effect. The ejected electrons are called photoelectrons. The current produced due to emitted electrons is called photocurrent.
What is difference between photoelectric effect and photovoltaic effect?
Photovoltaic effect is the generation of an electric current in a substance when exposed to light. The main difference between Photoelectric Effect and Photovoltaic Effect is that in Photoelectric Effect the electrons are emitted to open space whereas in Photovoltaic Effect the electrons enter a different material.
What is the main difference between photoelectric effect and Compton effect?
Complete answer:
| Photoelectric effect | Compton effect |
|---|---|
| 2. The photon transfers all of its energy to a single electron. | 2. A portion of the photon’s energy is transferred to a single electron. |
| 3. A low-energy phenomenon is the photoelectric effect. | 3. The Compton effect is a phenomenon that occurs at a mid-energy level. |
