The lowest frequency of light that can cause the release of electrons at the given work function is 6.78 x 10¹⁴ Hz.

Lowest frequency of the metal

The lowest frequency of the metal is calculated as follows;

E = hf

f = E/h

where;

  • E is the energy of the photon
  • h is Planck's constant

f = (2.8 x 1.6 x 10⁻¹⁹)/(6.63 x 10⁻³⁴)

h = 6.78 x 10¹⁴ Hz

Thus, the lowest frequency of light that can cause the release of electrons at the given work function is 6.78 x 10¹⁴ Hz.
