We live in the digital era. In this virtual world of technology, one might survive without oxygen but not smartphones. Cell phones have become a necessity for many people throughout the world. … Cell phones are the perfect way to stay connected with others and provide the user with a sense of security. In the … Continue reading “THE ELECTRONIC SAVIOURS MINIMIZING PHONE RADIATION THROUGH COW DUNG CHIPS”
Like every coin has two sides, so does mobile phones. The necessity of having mobiles cannot be denied but it is also releasing the harmful radiations that is affecting the body. How a simple cow dung chip can solve our problems is very aptly defined by these students. Isn’t it intruging? Watch the video for … Continue reading “Minimising Radiation effect from Mobile phones through Cow Dung chips”
Radiation can make the ice act like a liquid which favours the growth of organic molecules. The researchers from Hokkaido University in Sapporo, Japan found that ice in space behaves like a liquid at -2100C and -1200C temperature range. This favours the formation of the organic compounds that include prebiotic molecules along with dust for the formation of planets.
The big bang theory is known to be the first and most famous theory stating the evolution of the universe.
The quantum yield of the radiation induced process is known as the amount or number of times that a specific event happens per photon that is absorbed by the system. The event that happens is in terms of a chemical reaction.
Infrared spectroscopy is analyzing the infrared light which interacts with a molecule. Infrared spectroscopy can be done in three ways- by measuring the absorption, the emission and the reflection.
The ozone layer or ozone shield is a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet (UV) radiation. It contains high concentrations of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.
The Big Bang theory predicts that the early universe was a very hot place and that as it expands, the gas within it cools. Thus the universe should be filled with radiation that is literally the remnant heat left over from the Big Bang, called the “cosmic microwave background”
Black hole is the region of space which has an extremely intense gravitational field- so intense that no radiation or matter can escape from it. Not even the particles of light can escape from inside it.
Heat is transmissible. It flows from body to body. Transfer of heat takes place in all solids, liquids and gases. Heat transfer is possible only because particles like molecules and atoms that all matter is made up of.
Radioactivity was discovered by Henri Becquerel in 1896, while using naturally fluorescent minerals for the study of x-rays.Radioactivity is the particle that emit from the nucleus as the result of nuclear instability.
Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets; while the phenomena include supernova explosions, gamma ray bursts, and cosmic microwave background … Continue reading “Astronomy”
Hello Students, Parents and Teachers!
