remaining components of light are able to pass through the cut-off filters virtually unhindered. The areas between transmitted light (transmission) and filtered out light (absorption) are sharply distinct from [...] 380 nanometres to 780 nanometres. The short-wave, blue components of light are richer in energy than the red components and are refracted more strongly on refractive surfaces than long-wave light. How can [...] light source oscillate in waves which are scattered in all directions. A polarisation filter in a spectacle lens filters out all oscillating light waves which are not vertical, so that only vertically
