Under the photon theory of light, a photon is a discrete bundle (or quantum) of electromagnetic (or light) energy. Photons are always in motion and, in a vacuum, have a constant speed of light to all observers, at the vacuum speed of light (more commonly just called the speed of light...

In 1900, Max Planck suggested instead that photons must be particles because of the way radiation behaves. This opened the door for Einstein to suggest in 1905 that light is both particles and waves. His explanation is based on the photoelectric effect. This is the way a sheet of metal emit...
One of the outgrowths of this is that cosmologists now treat space and time as a single, unified structure known as spacetime – in which the speed of light can be used to define values for both (i.e. “lightyears”, “light minutes”, and “light seconds”). The measurement of the ...

Light has the properties of both a wave and particle, with the intensity varying based on the number of particles or photons. Light behaves in a variety of ways when it comes into contact with water, air, or other matter, where it is absorbed, reflected, or scattered. Courtesy of iStock...

Inside chloroplasts are plate-shaped structures called thylakoids that are responsible for harvesting photons of light for photosynthesis, according to the biology terminology websiteBiology Online. The thylakoids are stacked on top of each other in columns known as grana. In between the grana is th...
Light has many properties such as. 1: Reflection. 2: Refraction. 3: Polarization. Light has a dual nature. It can be considered as a packet of photons or matter or as a ray of light. Reflection is defined as Bouncing back of light from a reflective surface due to absorption of light ...
