Radiation of a certain wavelength causes electrons with a maximum kinetic energy of 0.62 eV to be ejected from a metal whose work function is 2.65 eV. What will be the maximum kinetic energy (in eV) with which this same radiation ejects electrons from another metal whose work function is 2.01 eV? Units are in eV.
The energy of the incident radiation is given by,
E = h c/ lambda
where, h is the plankc constant
c is the velocity of light
and lambda is the wavelength of the incident radiation.
This solution calculates the maximum kinetic energy of the ejected electrons with step-by-step workings.
