3. What is the importance of coral reefs? Coral reefs support marine organisms, protect coastal areas from tsunamis and storms and also support the tourism industry. They act as barriers and protect coastal regions from strong and powerful waves. 4. How do corals benefit humankind? Corals are ...
Australia's ARPANSA has published a news story, on March 17, 2021, about both reviews and… boasted that the reviews are "World-first reviews into 5G radio waves". There is no doubt that in science being "the first" is important. Any scientist interviewed by a journalist gets a question...
Let's find out about three different types of ultraviolet rays. The sun produces short light waves called ultraviolet rays. Lesson Quiz Course 17Kviews UV-A Rays Ultraviolet rays are often called UV rays for short, and there are three types. UV-A rays are the ones that you get exposed to...

are not that different from any other type of light, whether incandescent, fluorescent, or just the age old candle flame. The difference is that black lights emit most of their light waves just outside the range humans can perceive, in the Ultraviolet (UV) part of the spectrum. When […...

at slightly different points which will cause inaccurate viewed colors. This is correct by using an achromatic lens, which is simply two lenses (one positive lens and one negative lens) fused together , this creates a lens that transmits and focuses the different colored light waves to focus ...
Scattering Rayleigh scattering accounts for the majority (about 96 percent) of attenuation in optical fiber. Light travels in the core and interacts with the atoms in the glass. The light waves elastically collide with the atoms, and light is scattered as a result. Some scattered light is ...
