Homework Statement Light travels at different speed through different materials. If it travels at speed c1 in a medium of refractive index 1.2, what is...
It can be found that this velocity is faster than the light speed in vacuum c, which also increases with increasing the conical angle α. Figure 1a shows the key idea of the method proposed in this article that the input pulsed beam possesses a distortion-free (plane) phase-front but a ...
where c = speed of light in the material and co = vacuum speed of light. Light leaving a transparent medium can only escape the surface and be emitted when the angle of incidence to the surface is less than the critical angle Θc (measured from the normal to the surface). The critical...
in close agreement with the intrinsic speed that light must have from its own instantaneous position in space, derived by James Maxwell. The relative velocity between a light front and a moving target depends on the velocity of the target and causes light to travel a different distance than ...
Once the AOTM is acquired (as is simulated in Fig. 1 using a random independent and identically distributed (i.i.d.) scattering matrix model for a multiply-scattering medium, see Methods), it can be used for optical focusing inside the medium by several different approaches (Fig. 1d–p)....
Is the speed of light constant? The speed of light is a universal constant in a vacuum, like the vacuum of space. However, light *can* slow down slightly when it passes through an absorbing medium, like water (225,000 kilometers per second = 140,000 miles per second) or glass (200,...
One of the challenges in the field of multi-photon 3D laser printing lies in further increasing the print speed in terms of voxels/s. Here, we present a setup based on a 7 × 7 focus array (rather than 3 × 3 in our previous work) and using a focus velocity of about 1 m/s (ra...

How much "overhead" do home stakers have on each of these metrics before they'd be forced to upgrade? Fortunately these are easier upgrades to make, whereas my upload speed is heavily throttled and I'm already paying for the best Internet plan I can buy. There's the can of worms ...
