Plot a graph of angle of incidence, i in ° on the y-axis against angle of refraction, r in ° on the x-axis and draw the line of best fit. What conclusion can be drawn from prescribed practical ...

Negative refraction is a property of some artificial metamaterials and can be used to bring diverging rays back to a focus – allowing for the creation of a perfect lens. First proposed by the Russian ...

Negative refraction. The lens has been dreamt up by Vadim Cheianov and Vladimir Fal’ko of Lancaster University in the UK and Boris Altshuler of Columbia University in the US. It would consist of two ...
