Photoelectrons are observed when a metal is illuminated by light with a wavelength less than 383 nm. what is the metal's work function?

Work function of the metal is 3.24 eV.                                    

Explanation:

It is given that,

Wavelength,

Let W is the work function of the metal. It is given by using Einstein's photoelectric effect equation. It is given by :

Since,

So, W = 3.24 eV

So, the work function of the metal is 3.24 eV. Hence, this is the required solution.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

force tends to be low and long diustance masses are high
