the maximum wavelength required to cover photoelectric emission on a metal surface is 8.0 ×10^-7m the metal surface is irradiated with light of frequency 8.5×10^14 heartz determine the threshold frequency and maximum energy of the electron
Added by Stacy
Step 1
We know that the speed of light (c) is equal to the product of the wavelength (λ) and the frequency (f). So, we can rearrange the equation to solve for the frequency: c = λf f = c / λ Substituting the given values: f = (3.0 × 10^8 m/s) / (8.0 × 10^-7 m) f = Show more…

The minimum energy required for the emission of photoelectron from the surface of a metal is $4.95 \times 10^{-19} \mathrm{~J}$. Calculate the critical frequency and the corresponding wavelength of the photon required to eject the electron. $h=6.6 \times 10^{-34} \mathrm{~J} \mathrm{sec}$.
A metal surface illuminated by $8.5 \times 10^{14} \mathrm{~Hz}$ light emits electrons whose maximum energy is $0.52 \mathrm{eV}$. The same surface illuminated by $12.0 \times 10^{1+} \mathrm{Hz}$ hight emits electrons whose maximum energy is $1.97 \mathrm{eV}$. From these data find Planck's constant and the work function of the surface.
The photoelectric threshold wavelength of a tungsten surface is 272 nm. Calculate the maximum kinetic energy of the electrons ejected from this tungsten surface by ultraviolet radiation of frequency 1.45 $\times$ 10$^{15}$ Hz. Express the answer in electron volts.
