1.	How we can say that light have dual nature . Explain it plz??
Answer» Thanks yogita ingle This wave-particle duality is most clearly seen in “double-slit” experiments, in which either electrons or photons are fired, one at a time, through a pair of holes in a barrier, and detected on a screen on the other side.Light behaves as particle as well as wave. The photoelectric effect of light is a proof of particle nature of light. The interference pattern obtained in double slit experiment is an example of wave nature of light. Wave-Particle Duality is the possession of both wave-like and particle-like properties by subatomic objects. The fundamental principle of quantum theory is that an entity that we are used to thinking of as a particle (such as an electron) can behave like a wave, while entities that we are used to thinking of as waves, such as light waves, can also be described in terms of particles (in this case, photons).
