In the photoelectric effect, light (photons) ejects electrons from a material's surface, creating an electric current. The energy of each photon must exceed the material's work function for electrons to be emitted. The intensity of light affects the number of electrons emitted, while the frequency determines the kinetic energy of the emitted electrons.

Which phenomenon demonstrates a particle nature of light?
The photoelectric effect demonstrates the particle nature of light. In this phenomenon, light is shown to behave like a stream of particles (photons) by ejecting electrons from a material when it hits the surface.
What does light produce in a photoelectric effect?
In the photoelectric effect, light produces electrons when it strikes a material surface. The energy of the incident light is transferred to the electrons, causing them to be ejected from the material.
What effect does a plane mirror have on the speed of light?
A mirror has no effect on the speed of light, but it has a radical effect on thevelocity of the wavefront, because it reverses the direction of the normalcomponent of the velocity.
How can you prove that light is a particle?
The particle nature of light was demonstrated through experiments like the photoelectric effect and the Compton effect. In the photoelectric effect, light shining on a metal surface causes the ejection of electrons, suggesting that light is made up of photons (particles). In the Compton effect, X-rays scattering off electrons result in a shift in wavelength, supporting the idea that light behaves as particles when interacting with matter.
What are the three main effects of an electric current?
The main effects of an electric current are the generation of heat (thermal effect), the production of light (light effect), and the creation of a magnetic field (magnetic effect).
How does light effect plant growth?
Light effect plant in 3 ways , 1: blue and red light effect photosynthesis , Photo peroid effects flowering in plants , . Light of different color effect cell division and enlargement .
The scattering of light by a colloid is called?
The scattering of light by a colloid is called Tyndall effect. This effect occurs when light is scattered by particles within a colloid, making the beam of light visible due to the reflection and absorption of light by the colloidal particles.
What effect does a convex lens have on light?
It refracts light twice, such that the overall effect is that the light is converged. A ray diagram will help understand this.
Which phenomenon demonstrates a particle nature of light?
The photoelectric effect demonstrates the particle nature of light. In this phenomenon, light is shown to behave like a stream of particles (photons) by ejecting electrons from a material when it hits the surface.
What effect a prism have on light?
Prisms refract light.
Does angle effect red eye?
What effect does angle have on red-eye effect?: Angles refract light into your eye and into the lens cap causing the red. Angles of light effect red-eye by reflecting light in certain directions of your eye.
What is ment by raman effect?
Raman effect is change in the wavelength of light that occurs when a light beam is deflected by molecules.
Does light effect rust?
Light does not effect rust, rust is not an organism it is a chemical reaction between Oxygen and Iron.
What does light produce in a photoelectric effect?
In the photoelectric effect, light produces electrons when it strikes a material surface. The energy of the incident light is transferred to the electrons, causing them to be ejected from the material.
