The photoelectric effect is a quantum electronic phenomenon in which electrons are emitted from matter after the absorption of energy from electromagnetic radiation such as x-rays or visible light.
According to plank's Quantum theory radiant energy is neither emitted nor Absorb continuously but discontinuously in the form of small packets of energy called quanta.A quantum of energy as light is Photon. Now according to photoelectric effectwhen a photon of light radiations strikes the surface of metal surface. It transfer its entire energy to it.since only a particle can hit another particle and exchange its momentum,the photon of light which hits the electron(known to be a particle)must also have particle nature.
how will you use the particle theory to explain why a saturated solution at 30 degreecelsius can become dilute at 70degree Celsius
Diffusion is evidence for particle models because it causes diffusions
fully explain independent particle or single particle model as a factor responsible for nuclear stability
Neither, try again.
An individual point particle in the standard model is described in string theory as a mode of vibration of a string. If for some reason the mode of vibration of the string changed, the particle would change to a different one.
No. To explain the photoelectric effect, you have to think of light as a particle, not a wave. The fact that light can be both a wave and a particle is part of quantum mechanics, not classical physics.

Particle theory of light can explain Photoelectric Effect,Compton effect,Pair production.... wave theory of light can explain interference,refraction...
wave-particle duality a+
Einstein first proposed the idea of photons as discrete packets of light energy to explain the photoelectric effect. According to his hypothesis, light is composed of individual particles called photons that transfer their energy to electrons upon striking a material surface. Additionally, Einstein's explanation of the double-slit experiments involved the concept of wave-particle duality, stating that light exhibits both wave-like and particle-like properties.
