What is the theory behind dual nature of light . Explain .
Answers
Together Max Planck and Albert Einstein explained the photoelectric effect by assuming that light was actually a stream of little particles, or packets of energy known as photons or quanta. Scientists now believe that light is both a wave and a particle – a property which they term the wave-particle duality
The Dual Nature of Light
A. Light has a dual nature
1.Sometimes it behaves like a particle (called a photon), which explains how light travels in straight lines
2. Sometimes it behaves like a wave, which explains how light bends (or diffracts) around an object
3. Scientists accept the evidence that supports this dual nature of light (even though it intuitively doesn't make sense to us!)
B. Quantum Theory
1. Light is thought to consist of tiny bits of energy that behave like particles called photons
a. Particles explain how light travels in straight lines or reflects off of mirrors
