After you have modified some values, click a “calc” button to recalculate the field left of it. For a given vacuum wavelength λ0, the wavelength in a medium with refractive index n is λ=λ0/n. Generally, the refractive index depends on the optical frequency or vacuum wavelength (→ ...
A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium, such as air, water or any other liquid or solid matter, as it propagates away from the source of the sound. A water wave is an example of a wave that involves a combination of long...

Whereas, if the index increases with increasing wavelength (which is typically the case in the ultraviolet), the medium is said to have anomalous dispersion. 然而,當折射率隨著波長增加而增加時(通常在紫外光區發現),則介質被稱為擁有反常頻散。 LASER-wikipedia2 ...
There are three main properties of a wave: its velocity, wavelength, and frequency. Wave velocity (v) is how fast a wave propagates in a given medium. Its unit is meter per second. Check the speed calculator for more information about speed and velocity. Wavelength (λ) is the distance ...
phase improvement plays an essential role in breaking this ambiguity. Either a high solvent fraction or a high-resolution data are necessary for successful phasing. There are, however, many benefits to SAD phasing. First, it may be possible to determine the structure from a single data set, th...

To study the phase kinetics of colloidal mixture, the well-mixed colloidal solution with a one to one LEG4 to SQ2 ratio was prepared and confined in a rectangle capillary with a medium area fraction (\(\varphi \approx 15 \% )\), and subjected to uniform illumination to activate one coll...
