Polarization and Interference confirm light is a wave.
In some experiments, light appeared to have wave properties, but in others, it appeared to have particle properties. The two ideas were believed to be in conflict - light was believed to be either one or the other. However, today it is accepted that light has both particle and wave properties.
There are TWO THEORIES of light propagation, WAVE and PARTICLE. The WAVE theory shares commonality with waves in a Pond in that they are both represented by a SINE Wave. They each have an Amplitude and a Frequency.
The statement "light possesses two properties: photons and waves" is not true because photons are not a property of light: they're the way light is emitted and absorbed. The correct statement is "light possesses two properties: particles and waves." Other properties of light include intensity, propagation direction, frequency, polarization. More information: Wave/Particle duality of light is one of the longest running paradoxes in Physics. It's wave characteristics, as described by Schrodinger function, are well proven. It's particle characteristics are also well evidenced though only directly at short ranges and lifetimes. The original assumption that all light comes in Photon particles with mass came from gravitational lensing,- light bent by large objects. We now better understand about curved space time curving everything, massive or not, but light is still described as wave bundle /corpuscles. The Photon is not a 'property', the two characteristics current physics uses are are 'waves' and 'particles'. 'Light' is simply a limited section of the energy wave spectrum that happens to be 'visible' to many creatures living on planet earth.
the two things that determine the color of a light wave are its wavelength and the material it reflects from.

The wave model of light and the particle model of light.
Light possesses both properties of a wave and a particle. As a wave it is an oscillating electric and magnetic field. As a particle, light is a packet of energy that is treated as a point particle that does not have an electric field without a charge.
There are TWO THEORIES of light propagation, WAVE and PARTICLE. The WAVE theory shares commonality with waves in a Pond in that they are both represented by a SINE Wave. They each have an Amplitude and a Frequency.
Light exhibits refraction, diffraction, dispersion, and all the other properties of waves.
One is photo electric emission phenomenon. The other one is Raman effect.
If one polarizing filter is angled 90 degrees from the other, they will block all light.
