Ultraviolet (UV) light is a type of electromagnetic radiation on the electromagnetic spectrum. The frequency of UV light is higher than that ofvisible light. This means it has more energy, which makes its wavelength shorter. This increased energy causes chemical effects in many objects — such a...
Some concepts you'll be tested on include the mathematical equation relating frequency and wavelength, energy on the electromagnetic spectrum, and the different types of UV radiation. Quiz & Worksheet Goals In this quiz, you will be assessed on the: Minimum SPF sunscreen recommended for ...

The design of this highly efficient, ultra compact frequency converter was made possible by using full 3D modeling of the propagation of tightly focused, broadband light fields in nonlinear and birefringent media. The researchers developed an open source simulation package, called Hussar, that will ...
By combining stimulated Raman scattering and sum-frequency generation within a single laser system, indeed often within a single resonator, it is possible to achieve frequency conversion over a wide range of output wavelengths, that are useful for a number of applications. This paper reviews the co...
Germanium-doped silica fibers were prepared for frequency doubling of 1.06-microm wavelength radiation under the simultaneous presence of the first, second, and fourth harmonics of the laser light. It was found that the preparation rate for frequency doubling was dramatically increased by the presence...
Ultraviolet rays have frequencies greater than the frequency of visible light but lower than the frequency of X-rays. The wavelength of ultraviolet light is shorter than visible light and longer than that of X-rays. On interaction with human skin, ultraviolet rays can cause skin tan and burn....
