move it around the wearer and allow it to continue on the other side as if its trajectory had taken it, unopposed, straight through the person in the cloak. Now how
A refractive index is a dimensionless unit that relates the speed of light in a vacuum to the speed of light in the medium through which it travels. It is directly proportional to the speed of light in a vacuum and inversely proportional to the speed of ligh...
Which leads to a fascinating question: What if there are colors within the visible spectrum that our cones and brains can't see? In fact, there are. So-called impossible colors or forbidden colors break the biological rules of perception. But some researchers think they've discovered a way ...

core - thin center of the fiber where the light travels cladding - outer optical material surrounding the core that reflects the light back into the core buffer - a protective plastic coating applied directly to the optical fiber jacket - protective outer layer of the cable that protects the ...
One of the lens surfaces then reflects the light back to the detector at a different location. This ghost image is of interest because the ghost light is nearly focused on the detector, which will lead to a much brighter ghost image than if the light were spread out over a larger area....
Diamond cutters have to consider the Refractive Index (RI) and the Dispersive power. RI- the amount of incident light reflected back- is responsible for the brilliance of the diamond. Dispersive power is the ability of the diamond to split the white light into its spectral color called fire....
"To obtain an idea of the size of a light-year, take the circumference of the Earth (24,900 miles), lay it out in a straight line, multiply the length of the line by 7.5 (the corresponding distance is one light-second), then place 31.6 million similar lines end to end," NASA's ...
glass, car headlamps, etc. lead-oxide glass has a high refractive index, which enhances the quality of the look of glassware. the reason why it has a high refractive index is that it has a high density and thus high electron density. it also has a high elasticity which helps to make ...
