Maximum Kinetic Energy Calculator:
Enter the values of Planck’s Constanth(eV*s) , Frequency of the Incident Photon f(Hz) & Work Function (eV) to determine the value of Maximum Kinetic Energy Emax(eV) .
Maximum Kinetic Energy Formula:
The Maximum Kinetic Energy Emax(eV) in electron Volt is Equal to the Planck’s Constant h(eV*s) in electron Volt * second and Multiply to the Frequency of the Incident Photon f(Hz) in Hertz and is Subtracted by the Work Function W(eV) in electron Volt.
The Equation of Maximum Kinetic Energy can be written as,
Emax(eV) = h(eV*s) * f(Hz) – W(eV)
Here,
Emax(eV) = Maximum Kinetic Energy in electron Volt
h(eV*s) = Planck’s Constant in electron Volt * second
f(Hz) = Frequency of the Incident Photon in Hertz
W(eV) = Work Function in electron Volt
Maximum Kinetic Energy Calculation:
1) Calculate the Maximum Kinetic Energy and given for the Planck’s Constant = 4.14*10-15eV*s, Frequency of the Incident Photon = 10Hz, Work Function = 7eV.
Answer
Emax = h * f – W
Emax = 4.14*10-15 * 10 – 7
Emax = -7 eV.
2) Calculate the and given for the Planck’s Constant = 4.14*10-15eV*s, Maximum Kinetic Energy = -7 eV , Work Function = 7eV.
Answer
Emax = h * f – W
-7 = 4.14*10-15 * f – 7
f = 10 Hz.
