The phenomenon of forming an interference pattern by using light that passed through a double slit is a basic item learnt in a high school physics course. It is a good example that light possesses a ...

The simulation visualizes the intensity distribution of light on a distant screen after passing through one or two narrow slits. This is primarily based on Huygens' principle and the principle of ...

Electrons travelling through two slits and a single slit. (Courtesy: Herman Batelaan/New Journal of Physics) Physicists in the US and Canada say that they have done the best job yet of realizing ...

When a laser beam is incident on a narrow opaque object such as a fine wire or a strand of hair, the resulting diffraction pattern is similar to the diffraction pattern of a slit of the same width as ...

Researchers announced last week that they had slowed down faint pulses of laser light and retrieved an image from that light after speeding it back up. In principle such "slow-light" technology might ...

"These single atoms are like the smallest slits you could possibly build." For over 100 years, quantum physics has taught us that light is both a wave and a particle. Now, researchers at the ...
