Dual Nature Of Light
Introduction dual nature of light means light has tw different nature sometimes it behaves like a particle sometimes it behaves lik a wave.
Dual nature of light. Developing a theory to explain the nature of light was a difficult task. Albert einstein s photoelectric effect experiment proves that light can behave as a particle while thomas young s double slit experiment shows that it also behaves as a wave. It seems as though we must use sometimes the one theory and sometimes the other while at. Electrons and atoms were originally considered as corpuscles.
Light is neither considered a wave nor a particle instead it has characteristics of both a wave and a particle. We now see that light can also be modeled as particles massless photons of discrete energy and momentum. The dual nature of light is wave particle duality. Light is the electromagnetic radiation that can be detected by a human eye.
An acceptable theory in science is required to explain all the observations made on a particular phenomenon. As albert einstein wrote. I discuss a few of the famous experiments which establishes the natu e of light i e. We call this twofold nature the particle wave duality meaning that em radiation has properties of both particles and waves.
Get a quick overview of introduction to dual nature of light from introduction to dual nature and light as waves and particles in just 3 minutes. Light appears to have two different sets of behaviors under different circumstances. In 1929 prince louis victor de broglie was awarded the nobel prize for physics for his discovery of the wave nature of electrons. Dual nature of light.
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. Sometimes it behaves like a wave which explains how light bends or diffracts around an object 3. Light has a dual nature 1 sometimes it behaves like a particle called a photon which explains how light travels in straight lines 2. And it is within the certain portion of the electromagnetic spectrum called as visible spectrum.
Some experiments prove that light possesses characteristics of a wave while other experiments prove light is a particle.
