Light is a form of energy which enables us to see objects and the straight line along which it travels is called ray of light. Reflection of Light is the process of sending back the light rays which ...

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 ...

A ripple tank can be used to investigate the frequency close frequencyThe number of waves produced each second. The unit of frequency is hertz (Hz)., wavelength close wavelengthThe length of a single ...

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 ...

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 ...

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 ...

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 ...
