Rainbows need very specific conditions to be visible. The optimum conditions consist of a short morning or evening rain and a very bright sky. When this happens, a major part of the water droplets are still in the sky and the sunlight scatters through them and creates different colors depending on a range of factors. […]

Look where science has got us. We can fly. Imagine telling your ancestors a thousand years ago, or even five hundred years ago, if you could travel through time, that one day people would fly in enormous metal machines. Travel around the world in 80 days? First you would have to explain that the world […]

Statistics show that the average woman lives 7 years longer than the average man. The gap isn’t the same in all parts of the world, so the difference varies. For example, the average length of a man’s life in industrialized countries is shorter, because of the hazardous working conditions. Initially, scientists thought that the gap […]

Metal VS Non-Metal (Physical Differences)

  Nuclear Fission vs Nuclear Fusion

In the summer season, it is found that the air closer to the earth’s surface is hotter than the air found above it. This makes the air that is closer to the earth’s surface much rarer that the air found above it. So as we go up from earth’s surface, the air’s refractive index augments […]

When a beam of light passes through denser medium to a rarer medium it curves away from the normal at the point that divides the two medium. This happens due to refraction. The ray of light keeps moving away from the normal as the angle of incidence (θi) and the angle of refraction (θr) increases […]
