Plot a graph of sine of angle of incidence (y axis) against sine of angle of refraction. The gradient of this graph is the refractive index of the material of the semicircular block. So the ray ...
Experimentally verified thermodynamic model reduces relative uncertainty of previous model by over one order of magnitude.
Researchers at Harvard University announced recently that they had successfully developed a means of manipulating light at the nanoscale, which could lead to photonic-based (rather than electronic) ...
