Is Light A Particle Or A Wave

Since light has energy momentum and a wavelength and matter has energy and.

Is light a particle or a wave. But what is it really. Wave particle duality is the concept in quantum mechanics that every particle or quantum entity may be described as either a particle or a wave it expresses the inability of the classical concepts particle or wave to fully describe the behaviour of quantum scale objects. Light as a particle. It seems as though we must use sometimes the one theory and sometimes the other while at.

Light sometimes acts like a wave and sometimes acts like a particle depending on the situation. In the 1920s a young physicist named louis de broglie made a radical suggestion. If light were a wave strong light should cause photoelectrons to fly out with great power another puzzling matter is how photoelectrons multiply when strong light is applied. Matter is a wave and a particle.

Classically light can be thought of in two ways. Einstein explained the photoelectric effect by saying that light itself is a particle and for this he received the nobel prize in physics. This is the form of the wave equation. The textbook might start off with some experimental evidence from the historic.

Either as a particle or a wave. So maxwell s equations do say that light is a wave. This only makes sense if you accept that light is something more complex.
