Question

If titanium is irradiated with light of 233 nm, what is the maximum possible kinetic energy of the emitted electrons?

Answer 1

Answer:

K=1.61×10−19 J

Explanation:

In the question data given is as follows:

   Wavelength of the is given as light (λ)=233 nm

  while the worrk-function of the titanium given as (ϕ)=6.93×10−19 J

but for the energy imparted due to the light will now be

E=hcλE, then

E=hcλE=(6.63×10−34)(3×108) / 233×10−9

E=8.536×10−19 J

Now, the energy imparted is given by

E= ϕ + K

8.536×10−19= (6.93×10−19) + K

K=1.61×10−19 J

Then,

K is the kinetic energy of the electrons
