Sagot :
Light of wavelength 360 nm strikes a metal whose work function is 2.4 eV.
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.
