Stopping potential depend on the frequency of light, as per the wave model of light?
Stopping potential depend on the frequency of light, as per the wave model of light?
The correct option is B No
The wave model predicted that frequency should have no role in stopping potential.
Can you try recalling why?
It's easy right? what is stopping potential ?
It’s the volt required to stop the photocurrent.
How do you stop the photo current?
Well if you stop the electron with the highest energy from touching the collector plate, then my friend you have succeeded in stopping the photo current and, the negative potential at this point of time is called the stopping potential
So what will happen to this electron and its energy if I change frequency?
Welllllllllllllll…………..
Nothing right, the energy with which an electron comes out is equal to the energy it receives - the work function of the plate .
So to change the energy of electron I will have to change the energy falling on it. In the wave model this energy depends only on amplitude. I know this, the bald guy has repeated this so often that even if that's not true I am pretty much convinced that it is. :p
So yea that’s what the wave model predicted but turns out that's not what we observe.
