What is the difference between 1310 and 1550? 1550 loses slightly lower percentage of photons per distance compared to 1310, meaning on the same fiber link, 1550 can go slightly farther than 1310. All other things being equal, a 25km link at 1310 will lose about 8.75dB of light, while at 1550 will lose about […]

What is the role of light in photosynthesis?
What is the role of light in photosynthesis? Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. What is the product of water […]
Why is British heat so bad?
Why is British heat so bad? Extended periods of heat hit Britons harder because their bodies aren’t accustomed to high temperatures, meaning they rapidly overheat. Scientists say that people in Britain also ‘don’t know how to take care of themselves’ during heatwaves, staying out in the sun too long, and failing to drink enough water. […]
What is the difference between primary secondary and tertiary sources of information?
What is the difference between primary secondary and tertiary sources of information? Data from an experiment is a primary source. Secondary sources are one step removed from that. Tertiary sources summarize or synthesize the research in secondary sources. For example, textbooks and reference books are tertiary sources. Is interview primary source or secondary? Primary sources […]

Is Dark Matter growing?
Is Dark Matter growing? The total mass of dark matter is fixed, so as the Universe expands and the volume increases, the density of dark matter drops, just like it does for normal matter. As space expands, the dark energy density remains constant, rather than decreasing or increasing. Does observation affect reality? Summary: One of […]
