1. UV light is typically found as part of the radiation received by the Earth from the Sun. Most humans are aware of the effects of UV through the painful condition of sunburn. The UV spectrum has many other effects, including both beneficial and damaging changes to human health.
2. Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than soft X-rays. It is so named because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the color violet (purple).
3.We are applying UV light in our academy. First is the Security in our academy such as Credit cards, driver's licenses, passports, and rabii. Second application can be found in Fluorescent lamps that light up our academy.
4. Security in our academy. UV light help thwart counterfeiters, sensitive documents (e.g. credit cards, driver's licenses, passports, and rabii) may also include a UV watermark that can only be seen when viewed under a UV-emitting light. This way we can be sure that no intruders can get in and out of the academy and that we are not using fake rabii.
Fluorescent lamps that light up our academy. A phosphorescent coating on the inside of the tubes absorbs the UV and converts it to visible light. Now we can continue doing our activities in school without having any problems in our lighting.

Here's my second assignment sensei. ^^

Well explained, UV light has the shortest wave length of all light actually. It is much shorter than violet (not purple).

Hand me in ASAP, the penalty will be as follows:
1~3 days late, minor punishment
4~7 days late, intermediate punishment
>7 days late, severe punishment
The punishment will be decided on the work you have submitted and the quality of the work.

P.S: If you need to take a leave, please tell me about it and show me the "MC".
