SUMMARY
The threshold frequency of a metal with a work function of 7V can be calculated using the formula f = W/h, where W is the work function and h is Planck's constant. To convert the work function from volts to joules, it is essential to use the relationship that 1 volt equals 1 joule per coulomb. Therefore, the work function of 7V translates to 7 joules per coulomb, which corresponds to 7 joules per electron when considering the liberation of one electron per photon. This conversion is crucial for accurately determining the threshold frequency.
