1) Photo-electric effect.
2) Spectrum of black-body radiation.
3) Compton scattering spectrum.
4) Disappearence of interference pattern with two slits, if a way is made to determine which slit the light went through.
All three of these can be easily explained by assuming that light is composed of photons, and that the energy of those photons is proportional to the frequency of the light. None of three can be explained by assuming light is purely an electro-magnetic wave.
Light is made up of particles called photons, which are packets of energy. These photons have no mass but they do have momentum and behave both as particles and waves. So in a sense, light can be considered a form of particulate matter.
Light is said to exhibit wave-particle duality because it is observed to behave as both a wave and a particle. When we shine light into narrow slits, the phenomenon of interference occurs and leads us to believe that light behaves as a wave. On the other hand, if light is shone on a metal, the spray of electrons indicates light behaves as a particle. This is the dual nature (wave and particle) behaviour being referred to. Hope this helps!
Source and state are just two of the categories used to classify particulate matter. So, source identifies the origin as human- or nature-made while state indicates configuration as a liquid or solid.
Blackbody radiation has particle character because it is composed of photons, which are quantized and behave like particles. Photons are the elementary particles responsible for carrying electromagnetic radiation, including visible light and other forms of electromagnetic waves. This particulate nature of photons is a fundamental aspect of quantum mechanics.
== == Study of Light & Nature of Light is called " OPTICS "
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.
No, it's not. But there are two theories as to the nature of light. One says it's a wave-form and the other says it's particulate. Both theories hold water in that they can be used to deduce the expected behaviour of light under different circumstances.
The particulate nature of matter is maintained through the structure of atoms and molecules. Matter is made up of tiny particles such as protons, neutrons, and electrons that are arranged in specific configurations within atoms. These particles interact with each other to form the various substances we encounter in the world.
There are several pieces of evidence for the wave nature of light, including interference patterns observed in double-slit experiments, diffraction patterns when light passes through small openings, and the fact that light can be polarized. These phenomena can only be explained by treating light as a wave with properties such as wavelength and frequency.

The question is not so clear.

Yes, they do indeed make venetian blinds that are light proof to prevent light from entering the room. They are extremely expensive.
Light waves are transverse in nature.
The film is light sensitive and if it wasn't in a light proof cassette then the film would be surrounded by light so the picture that it takes would be ruined.
The particle nature of light is illustrated by the photoelectric effect.
