Question

Which equation links the work function to the threshold frequency?

विकल्प

• \[\phi=h+\nu_0\]

• \[\phi=h\nu_0\]

• \[\phi=\nu_0-h\]

• \[\phi=\frac{h}{\nu_0}\]

Answer 1

At the threshold frequency, photon energy equals the work function: \[\phi=h\nu_0\]. This relationship is used to calculate \[\nu_0\] from the work function.
