Dependent variable is the angle of refraction. Control variables are the material of the block, the shape of the block and the colour of the light. Remember - these variables are controlled (or ...

For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays—without the ...

Among the most sought-after properties of metamaterials is the negative index of refraction of light and other radiation. Negative refraction is based on the equations developed in 1861 by Scottish ...

In a gradient, light bends towards the higher-index part, as the law of refraction predicts, or according to Fermat's principle. In a homogeneous medium (top and bottom), light does not bend. Mix up ...
