Exploiting a novel technique called phase discontinuity, researchers have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction. The discovery has ...

At the interface between two facets of an artificial crystal, sound waves can be transmitted in the opposite direction to that expected, and undergo no reflection. Such wave behaviour could have ...

Students use mirror equations to determine the position and type.

In my previous Photography Snapshot, I discussed the importance of light and how it bounces to create images. In this Snapshot we will discuss the difference between reflection and refraction, how ...

Total internal reflection inside a 45 o glass prism. The critical angle close critical angleThe critical angle is the angle of incidence in the dense medium when the angle of refraction in the ...

The effective index of refraction extracted from the transmission and reflection now displays a negative band that is associated with the double negativity, since both the effective ...
