1
Every time a helium nucleus gets created, particles of light called photons get made.
2
The cockroach is quite marvellous Light is made up of unimaginably tiny particles called photons.
3
It would not be until the 1920s that particles of light would be called photons.
4
Light particles - called photons -carry a packet of energy that depends on their frequency.
5
The electromagnetic attraction is pictured as being caused by the exchange of large numbers of virtual particles called photons.
6
Particles of light, called photons, feel no drag at all, and so remain massless and keep moving at the speed of light.
7
At the same time, Einstein proved (he's ubiquitous in this arena) that light sometimes acts like particle BBs called photons.
