The earth’s atmosphere is a strange and miraculous layer which is the main reason for many of the beautiful landscapes we can see from earth. We won’t be exaggerating if we say that the sky is probably one of the most beautiful things you can observe from earth without any special equipment. In most cases […]
What’s Inside Camel Hump?
When you were a child, you have probably heard that camels use their humps to store water. However, this isn’t entirely true. The hump is in fact a mound of fat which can weigh up to 35 kilograms. Humans and just about all types of animals store their fat in their muscle tissue and beneath […]
Why are Manhole Covers Round?
Every one of us has seen manholes – these are the round openings which connect the sewerage pipes of our city or village. However they serve a much higher purpose – manholes are used as an entry point for pipe cleaning. Each manhole is covered with a round cover in order to prevent accidents.
Difference between Nuclear Fission and Nuclear Fusion
Nuclear Fission vs Nuclear Fusion
Astronomical Telescope
An Astronomical telescope is utilized for the observation of heavenly objects that are at great distance in relation to the earth. These include stars and planets. Due to the great distance, they appear very small in size and nearer to each other.
Defects of Vision
An object is viewed clearly only when the image forms exactly on the retina. It is the distance of the object that dictates as to how thick the eye’s lens is going to be. This thickness of the lens is modified by a special form of muscle called ciliary muscle.
What Causes a Mirage
Twinkling of Stars
Why Do Stars Twinkle? Because of the difference in densities among the layers of atmosphere, the density of the atmosphere as a whole is not consistent. The layer at a higher altitude is less cold and denser than the layer present at a lower altitude. Because of this as we go upwards, the refractive index […]
Total Internal Reflection Definition

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 […]
