The process through which light rays falling on the surface on an object are sent back is called reflection of light. Thus, when light falls on the surface of an object it sends back the light. The ...

The glasswing butterfly (Greta oto) has, as its name suggests, transparent wings with remarkable low haze and reflectance over the whole visible spectral range even for large view angles of 80°. This ...

When a ray of light is incident at normal incidence, (at right angles), to the surface between two optical materials, the ray travels in a straight line. When the ray is incident at any other angle, ...

There are different ways to investigate refraction in rectangular blocks. In this required practical activity, it is important to: make, measure and record the angles of incidence accurately using a ...

Rainbows are circular bands of light formed by the refraction and reflection of sunlight through water droplets. The colors are always in the same order: red, orange, yellow, green, blue, indigo, and ...

Schematic of a grazing incidence small and wide angle X-ray scattering (GISAXS/GIWAXS) experimental setup showing the incident (αi) and the scattered angles along the horizontal (2θf) and vertical (αf ...

The calculation of reflections at low angles is an essential component of multiple procedures that involve compounds with extensive structural properties. These compounds have gained attention within ...

McPherson (Chelmsford MA USA) is pleased to announce a new vacuum ultraviolet spectral test system VUV-STS. The new system measures reflectance as a function of angle of incidence. It measures optical ...
