The work function of titanium metal is 6.93 × 10⁻¹⁹ j. calculate the kinetic energy of the ejected electrons if light of frequency 1.216 × 10¹⁵ s⁻¹ is used to irradiate the metal.

6.81*10^-20 J

Explanation:

The energy from the light does two things: it removes the electrons from the surface of the metal and the rest is taken up as kinetic energy by the electrons.

K.E = hf - work function
