the Particle model is same as god leaf model ?

What do you mean by god leaf model? Have not heard of it.

Are you dealing with Nuclear physics or Quantum physics?
Quantum Physics

i have photo of it and its quite complicated
I believe there are few question on it as well
I am not able to attach a photo here

but it explains how intensity and frequency effect the Kinetic Energy and no of photon-electrons ejected
not really explains but gives you idea

i am not sure what particle model is, could you explain if you know ?

The detail would be best that you seek out some educational sites.
The following website would “explain” the concept in detail.

In physics, there are three well-known models of light:
(1) ray model
The basis of the ray model of light is that light travels in straight lines. The ray model of light is valid as long as any apertures through which the light passes (lenses, mirrors, and holes) are very large compared to the wavelength of light.
(2) wave model
The wave model of light well explains the phenomenon of diffraction and interference. When light passes any apertures and experiences significant diffraction, the wave model is a better description.
(3) photon model (aka particle model)
In the quantum world, light is modelled as photons (“quantum particle” not classical particle) that have both wave-like and particle-like properties. Light behaves like neither a wave nor a particle. Many photon visualisations in A level physics or university physics tell only half the story because there is no “true” representation of a photon. Analogies such as raindrops or wave packets can be useful, but none is perfectly accurate.
The following website(s) explain the photon model in a bit more detail.

Thank you so Much

i will get over these sites
are you a student or a teacher as i am not able to acess enough past paper to practice
exam builder would be really helpfull if you have access to it
Regards

You may want to look into the following website to access the past papers of your examination board.
