Does work function depend on wavelength of incident light?
Yes, the work function is the minimum amount of energy required to remove an electron from the surface of a metal. The wavelength of incident light can indirectly affect the work function through the energy of the photons, with shorter wavelengths having higher energies.
What is a semiconductor device that produce electric current through the photo-voltaic is an?
A semiconductor device that produces electric current through the photo-voltaic effect is a solar cell. When sunlight shines on the cell, it creates an electric current by releasing electrons from the material. This electric current can then be harnessed for various applications, such as generating electricity for homes or powering electronic devices.
Einsteins equation of photo electric effect?
1. hv=hvo + 1/2mvo2here h= plank's constantv= cut off wavelengthvo=cut off frequencym= massvo=stopping potential
Why ultraviolet light is used in photoelectric effect?
Just visible light too can be used for photo electric phenomenon. But Hallwachs used UV rays as he used zinc plates. That is all. Moreover the energy of the photon has to be more than the work function of the material being used.
What Thermodynamic state function measures the maximum electric work in a fuel cell?
Gibbs free energy is the thermodynamic state function that measures the maximum electrical work that can be obtained from a fuel cell at constant temperature and pressure. It represents the balance between the system's enthalpy, entropy, and temperature.
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.
What is photo electric?
when photons got enough energy and getting out from that meterial electric current produced from that movement called photo electric.
Are alkali metals suitable for photo electric emission?
yes alkali metals are suitable for photo electric emission
What are the release dates for How Machines Work - 2010 Thames Flood Barrier Electric Locomotive Gas Pump Photo-Finish Camera 1-8?
How Machines Work - 2010 Thames Flood Barrier Electric Locomotive Gas Pump Photo-Finish Camera 1-8 was released on: USA: 16 April 2010
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 working principle of photoelectric transducer?
photo electric transducer
How does electric current make electrical appliance work?
Electric current is the flow of electric charge through a conductor, such as a wire. When an electrical appliance is plugged in, the electric current flows through the appliance's circuitry, providing the necessary energy for the appliance to function. The current powers various components within the appliance, such as motors, heating elements, or lights, allowing it to perform its intended function. In essence, electric current is the driving force that powers electrical appliances and enables them to work.
Does electric work when power cord is not attached to device?
No, an electric device will not work if the power cord is not attached as it needs the electricity provided by the cord to function. Without the power cord, there is no source of electricity to power the device.
What has the author David William Cornelius written?
David William Cornelius has written: 'The study of the velocity of electrons in the photo-electric effect, as a function of the wave-lengths of the light' -- subject(s): Electrons, Radiation
What is the function of resistor in electric circuit?
the function of a resister is to lower the voltage.
What is photo transistor?
Photo transistor always work with solar power
