Hello students, subscribe to this question, we know that hmue equal to kinetic energy plus phi.
00:13
So in graph, so phi is the work function.
00:23
So in graph b, electron requires a certain amount of energy.
00:28
Firstly, we can draw the graph.
00:42
So we can conclude that in graph b, it requires a certain amount of energy.
00:49
To get out of atom and at the moment it does not have any kinetic energy.
00:55
So the minimum energy is called the work function.
00:58
If we give energy more than this, so electron will have kinetic energy...
