In the photoelectric effect, it is found that incident photons with energy 5.00ev will produce electrons with a maximum kinetic energy 3.00ev. what is the threshold frequency of this material?

The threshold frequency of this material is

Explanation:

It is given that,

Energy of incident photon, E = hυ = 5 eV

Maximum kinetic energy of electrons,  

We have to find the threshold frequency of this material. Einstein photoelectric equation gives the relationship between energy and threshold frequency i.e.

............(1)

where

is the threshold frequency of this material.

h is Planck's constant,

Putting all values in equation (1) as :

Hence, the threshold frequency of this material is                                                                             

its c i just checked it

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
