Figure 1: Diagram and SEM image of fabricated fishnet structure. Here we experimentally demonstrate the first 3D optical NIM by directly measuring the angle of refraction from a prism made of cascaded ...

Plot a graph of angle of incidence, i in o on the y-axis against angle of refraction, r in o on the x-axis and draw the line of best fit. We can see from the graph that as the angle of incidence, i, ...

In my previous Photography Snapshot, I discussed the importance of light and how it bounces to create images. We discovered that the most primitive form of photography was the camera obscura, which ...

A light ray is traveling in a transparent material of refractive index 1.51 at an angle of incidence of 38 degrees and approaches a second material of refractive index 1.46. Solve for (a) the angle of ...

Welcome to science world! Today, we're going to have a look at a particular type of wave - a light wave. Who knew so many different things travelled in waves? A light wave travels faster than anything ...

Refractometers are versatile in their design and use, and are able to provide results as refractive indices, or in other cases, as direct measurements of parameters such as soluble solids, sugar ...
