1. you have a book so use it ok ?2. re-read number 1 ♥ (:
The photoelectric effect was pretty definitive evidence that light is a particle (well, at least sometimes a particle).
Light is sometimes described as a wave and sometimes as a particle. Give evidence to support the wave of natural light
Light is both a wave and a particle depending on circumstances; this is referred to as the wave-particle duality of light.
Yes. Light has both particle and wave properties.
There are three main pieces of evidence to support the Kinetic Theory of Matter1) Brownian Motion 2) Diffusion 3) Thermal Expansion:) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :)Thanks guys xxHope this helps!!Good Luck! xx

Light travels in a straight line, and it cast a shadow.

Newton believed that light is made up of particles, period.

Electrons can produce light when they are "excited," and jump outside their ground state, then hop back, releasing a photon of light.

The particle nature of light is illustrated by the photoelectric effect.
Albert Einstein's Photo-electric effect is one of the proof of the particle nature of light. The experiment on the wave particle duality is another proof pf the particle nature of light.
The duality of light is mainly a concept, brought on by empirical evidence that suggested that light could behave and can much like both a wave and a particle. It began with the wave theory of light. The wave theory predicted that light waves could interfere with each other like sound waves, and that light could be polarized, if it were a transverse wave. Thomas Young's two-slit experiment showed the diffraction of light. His experiments supported the theory that light consists of waves as waves were shown to have diffracted through slits. Although the particle theory of light had been suggested before the wave theory, it was never taken seriously into account, until now. Experimental evidence of the photoelectric effect, by which light striking a metal surface ejected electrons from the surface, causing an electric current to flow across an applied voltage. Experimental measurements demonstrated that the energy of individual ejected electrons was proportional to the frequency, rather than the intensity, of the light. Furthermore, below a certain minimum frequency, which depended on the particular metal, no current would flow regardless of the intensity. These observations clearly contradicted the wave theory, and for years physicists tried in vain to find an explanation. In 1905, Einstein solved this puzzle as well, this time by resurrecting the particle theory of light to explain the observed effect. Together, with more empirical evidence supporting both wave and particle characteristics, they formed the basis for wave-particle duality and much of quantum mechanics.
