Answer 1

Answer:

Here The work function of a photoelectric material is 3.3 eV. So, we have to determine the threshold frequency.

According to the question,

We know,

W=hv

V=W/h

=(3.6×1.6×10^-19)/(6.6×10^-34)

=8×10^14 Hz.

So, solving the problem with the equation W=hv we can get the value of V. Here V is threshold frequency, and by calculating after putting the values we can determine the V.

And in this case V=8×10^14 Hz.

So, the threshold frequency is 8×10^14 Hz.
