The phenomenon of light behaving as both a particle and a wave challenges traditional understandings of its nature by defying the classical idea that light can only be one or the other. This duality suggests that light has properties of both particles and waves, leading to a more complex and nuanced understanding of its behavior.

The photoelectric effect is the emission of electrons when light shines on a material. This phenomenon supports the idea of light behaving as a particle (quantum) because it shows that light energy is quantized and can transfer a discrete amount of energy to electrons in the material, causing them to be emitted.
The wave-particle duality of light is the concept that light behaves both as a wave and as a particle. When behaving as a wave, light exhibits phenomena like interference and diffraction. When behaving as a particle, it interacts with matter in discrete packets called photons.
The observation of interference patterns in experiments such as the double-slit experiment, where particles exhibited wave-like behavior by creating interference patterns, led scientists to describe matter as behaving like a wave. This behavior is characteristic of wave properties, suggesting that matter can exhibit both particle and wave-like behavior depending on the experimental setup.
"Come off it" is an informal expression that means to stop saying something that is not believable or to stop behaving in a way that is unreasonable. It is often used to dismiss an unrealistic statement or request.
Boyle's law assumes that temperature is constant, the gas is behaving ideally, and the amount of gas is fixed. It also assumes that the pressure and volume of the gas are inversely proportional to each other.
