Alternatively, transmission and reflection occur once the frequency of light will not match the frequency of the normal vibration of the electrons. When light enters a material with higher refractive index, the angle of refraction will be smaller than the angle of incidence and the light will be refracted towards the normal of the surface….
Using this theory, Heron of Alexandria advanced the argument that the speed of light must be infinite, since distant objects such as stars appear immediately upon opening the eyes. Some physicists, notably João Magueijo and John Moffat, have proposed that in past times light traveled much faster compared to the current speed of light. This…
Because of their different speeds in the glass, the red and blue light get bent at different angles if they go in to the prism. These yellow light times are not statutory requirements which you can use as a defense in a court of law. [newline]But they do give a rule-of-thumb when initially evaluating whether…
The setup as utilized by Fizeau consists of a beam of light directed at a mirror 8 kilometres away. On the way from the source to the mirror, the beam passes through a rotating cogwheel. At a certain rate of rotation, the beam passes through one gap on the way out and another on the…
The speed of light in glass can never be the same with that in air. Browse other questions tagged optics visible-light speed-of-light energy-conservation refraction or ask your personal question. Because neutrinos have a little but non-zero mass, they travel through empty space very slightly more slowly than light. However, because they pass through matter much…
The light bends towards the standard line so the angle of refraction is significantly less than the angle of incidence. The volume of bending for confirmed angle of incidence depends on the material. The table below lists index of refraction values for a number of medium. The imaginary part then handles the attenuation, as the…
