Diffraction of light Waves

Diffraction of light Waves

The wave nature of light leads to two very important properties: refraction, where the direction of light propagation is altered at the boundary between media of different densities, and diffraction, which has among its consequences that light can bend around corners . Refraction of Light The direction of light propagation can be changed at the boundary of two media having different…

Diffraction of light Physics

Diffraction of light Physics

The illustration shows the diffraction of light. The light comes from the light source on the right and is on the way to Earth (left). Between Earth and the light source is a large heavenly body, which causes the light to diffract its route towards the Earth. The orange arrows show where the light source…

Universe information theory

Universe information theory

On What if the fundamental “stuff” of the universe isn’t matter or energy, but information? That’s the idea some theorists are pursuing as they search for ever-more elegant and concise descriptions of the laws that govern our universe. Could our universe, in all its richness and diversity, really be…

Hologram Concerts

Hologram Concerts

There’s been a disturbance in the music world force. I pay an exorbitant ticket price, parking fees and sucker fees to see a live concert, but instead of real people performing, I get a hologram. As somebody who loves holograms, it saddens me to have to say this: using holograms to raise the dead or…

White light diffraction

White light diffraction

Diffraction effects depend on the wavelength of the light. Considering a single narrow slit with monochromatic light, light with wavelengths much larger than the slit will not be transmitted and light with wavelengths much shorter than the slit will be transmitted without significant diffraction effects, but light with wavelengths comparable to the slit will show significant diffraction…

Phones with Holograms

Phones with Holograms

In five years, cell phones will be able to produce holograms of friends and colleagues talking and moving in real time, IBM researchers say. In the mock-up photo provided by IBM, 3D video technology is used to create a hologram on a speakerphone. We see 3D [video] technology moving into the cell phone, which will have the ability to transmit information off the cell phone to create…

Two dimensional world

Two dimensional world

For all we know, the three dimensional world we see around us is really an illusion — one that’s actually in 2D. It’s a slightly unsettling idea, but it’s also one that physicists have been thinking about for some time. Unfortunately, until recently, a 2D universe wasn’t something we could verify. Now, thanks to an experiment recently launched at Fermi National Laboratory in Illinois…

CD diffraction

CD diffraction

The information on a CD is stored on a very thin shiny spiral track. When light shines on these thin lines it is diffracted in all directions, the light from neighbouring lines interferes constructively when the sin of the angle=λ/d. This means that different colours of light are seen at different angles. This is what causes the coloured patterns that you might have seen. In this…

Hologram Keyboard iPhone 5

Hologram Keyboard iPhone 5

Just look at those holographic images. ralphardi/YouTube Screenshot: Chris Matyszczyk/CNET New Yorkers are over-excitable. So when they see folks already lined up to buy the iPhone 5, they come over extra-giddy. Who, therefore, could blame Fox 5 New York from rushing out to interview the sad, money-grabbing self-publicists who are already adorning the Apple Cube, waiting for the…
