Natural Phenomena
Natural Phenomena happens almost daily in our lifes, but have we wondered why? What are these and Why they happen? Lets have a look!
1.Rainbow:In many traditions, rainbows are a symbol of peace and happiness. Some people used to say that unicorns make rainbows, something that it was made by leprechauns and they used to hide a board of gold at the end of the rainbow,but there is no science in it. Leprechauns and unicorns are mythical creatures also there at rainbows don't have beginnings or endings. Mostly people say that they must have seven colours red ,orange ,yellow ,green ,blue ,Indigo and violet but they don't know that there are two more colours which cannot be seen with a naked eye which means that there are nine colours. The last two colours are ultraviolet . Not many people have spotted this but the sky under a rainbow has a lighter colour than the sky above. Rainbow are formed by the process of refraction. If a ray of light meets a new material at a new angle, it bends,and this process is called refraction. People say that they have seen rainbows around the moon or in the cloud but they're not rainbows. The rainbows which is formed with the reflected light rays of moon through water droplets it's called a Moonbow and a cloud bow won is formed by frozen water droplets and light.
2. Lightning:
Lightning is an electrostatic discharge taht occurs from a thunderstorm. Thunder storm occurs when cool air rises and water vapors condense and form clouds. After condensation will occur, heat energy is relaesed which helps the thunderstorm grow. The things that are needed for a thunderstorm are moisture, unstable air and warm air that can rise rapidly. You can tell how far a lightning blasts away from you with the help of sound. Sound travels slower than light, so to find out how far you are away from lightning flashed by first looking at the flash of lightning and count the seconds until you hear the sound if you are 3 seconds awayof it than you are safe, if two seconds you are still safe, if only one second then it is not safe. At the time of thunderstorm it is best not to use electrical appliances. Benjamin Franklin did a kite experiment which made him know that lightning is electricity with a little assistance of a son.
3. Lunar Eclipse:
A lunar eclipse occurs when the moon passes directly behind the Earth into its shadow. This occurs only, and the sun, earth and moon are aligned exactly at the same point. This gives the moon and mysterious orange colour because the Earth's shadow blocks the rays of the Sun and can occur only on a full moon. The orange light is reflected from the Sun, if the Earth had no atmosphere, the mood would have been completely dark. The lunar eclipse is sometimes called the blood moon . When Christopher Columbus came to Jamaica, he needed food from the inhabitants that live there but they refused. He wanted the inhabitants to think that he had God like powers and he did, wuth the help of Europeean scientists understandings, He correctly predicted the lunatic eclipse , but afterwords begged him to return the moon. When the moon came back, the inhabitants gave him and his soldiers the food they needed.
