But the exact nature of light, and how it travels, has long puzzled scientists. One question in particular has vexed thinkers from Issac Newton to Albert Einstein: Is light a particle or a wave?

The inherent contradiction in the way energy behaves. At the turn of the 20th century, it was believed that light was electromagnetic waves and electrons were particles. By the 1930s, it was ...

Quantum entanglement comes in a new form, one that could be used to make quantum information technology smaller, once it ...

Electrons are particles. Sub atomic particles that is, which opens them up to this wave-particle duality property of nature. If we look at electrons as a particle, there is no way for them to move ...

Some of the key concepts of quantum physics are that particles like electrons can behave as waves, and vice versa (known as wave-particle duality ... state at a time: a light switch is either ...

A long-elusive, hypothetical subatomic particle called the axion can be simulated and potentially detected in a type of thin material.

If you adjust the light beam to accurately measure ... This stated that there was a dual nature to things -- an electron was a wave and a particle, for example -- but we could only perceive ...

If a clean, positively charged zinc plate is exposed to intense white light it will not discharge. If a clean, negatively charged zinc plate is exposed to intense white light it will not discharge.
