Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

Plot a graph of sine of angle of incidence (y axis) against sine of angle of refraction. The gradient of this graph is the refractive index of the material of the semicircular block. So the ray ...

Few people today would dispute that the use of Mie Theory provides the only route to accurate particle size analysis when measuring fine particles using laser diffraction. The international standard ...

Based on: The Determination of the Refraction of the Eye with the Ophthalmoscope. By Edward G. Loring, M. D. New York: Wm. Wood & Co. 1876.

Recent experiments that demonstrate the negative refraction of light could bring a heated scientific debate to a close, and give negative-index materials a positive future Figure 1: Negative-index ...

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 ...

Pigments and paints play a key role as industrial materials. The properties of a given pigment/paint system are determined largely by the particle size distribution. Particle size determines the ...

GRAND RAPIDS — Every day we see and use light for numerous daily functions, but did you know you can actually bend light? Its called refraction and our experiment today is going to show you how its ...
