Question

Ultraviolet light is typically divided into three categories. UV-A, with wavelengths between 400nm and 320nm , has been linked with malignant melanomas. UV-B radiation, which is the primary cause o f sunburn and other skin cancers, has wavelengths between 320nm and 280nm . Finally, the region known as UV-C extends to wavelengths of 100nm . 1.)Find the range of frequencies for UV-B radiation. fUV-Bmin,fUV-Bmax=________ Hz 2.)In which of these three categories does radiation with a frequency of 7.9 belong? A, B, or C

Explanation / Answer

Ultraviolet Light frequency range: 7.5 x 10^14 to 3 x 10^17 Hz b min 1.07*10^15 b max 0.93*10^15 radiation with a frequency of 7.9 belong? A, B, or C ( incomplete data) mean absence of 10^? From the wavelength you can determine the frequency. If you divide the speed of light by the wavelength, you can calculate the frequency.
