Chinese Scientific Team Claims Speed of Light Reduced by 10 Times: Can you reduce the speed of light 10 thousand times without losing energy. This can happen and scientists from the Chinese Academy of Sciences and Guangxi University have done this amazingly by claiming that this can have revolutionary benefits in optical communication and computing. Of course this small question may seem strange but it has great significance.Light travels at a speed of 299792 kilometres per second in space or vacuum, even if someone puts obstacles of electromagnetic field in the path of light. For example, if normal matter is added, the speed of light starts slowing down.
Has worked to give a new direction to the interaction
Most transparent materials are able to slow down the speed of light very little and due to the change in speed the light can be changed from one medium to another, but to reduce the speed of light significantly, photonic crystals or very Cold quantum gases will be required.In the study published in Nano Letters, the researchers wrote that they believe the work provides a new direction for the powerful light-matter interaction in nanophotonic chips.
Based on Electromagnetically Induced Transparency
The new method is based on Electromagnetically Induced Transparency (EIT). In this, a small amount of gas was interacted with electrons in the vacuum of the laser due to which it became transparent from opaque, that is, here the laser light can pass, but at the same time it also becomes slow.This is a very important achievement for physicists and other scientists because the slowing down of the speed of light means that a lot of energy is also being lost in this process.
Two-dimensional structure not found anywhere else in natureT
Researchers used new material to save energy. This material, called meta-surface, is made of thin synthetic layers of silicon and its two-dimensional structure is not found anywhere else in nature. Based on the results, researchers have found that the speed of light can be slowed down 10 thousand times.With this the travel of light can be controlled. In the future, its benefits can be seen in everything from broadband internet to quantum computing.
