Answers to the Javed- Farhan Akhtars song from Rock on.
Aasman hai neela kyon? – This is due to dispersion of light, technically called Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths ( red, yellow, orange) pass straight through however, the shorter wavelengths ( blue) are absorbed by the gas molecules and then radiated in different directions. This scattered blue light is what makes aasman neela .
Paani geela geela kyon? – Simple principles of adhesion, cohesion and surface tension apply here.Water’s molecular structure makes it good at forming hydrogen bonds and bipolar bonds with other materials. That's why it's so good at adhesion (sticking to things). Liquids like water, alcohol and kerosene have less surface tension and low viscosity so they wet the skin, leaving a thin viscous residue on the surface. ON the other hand liquids like Mercury with high surface tension don’t wet .
Gol kyon hai zameen? – The circular shape is due to the gravitational pull of the earth. It pulls all nature towards its core resulting in a shape that is circular.
Silk mein hai narmi kyon? – Silk is manufactured from the nest of silkworm,which is made up of liquid secreted by silkworm,It is not fibre like cotton so is much softer.
Aag mein garmi kyon? – Fire creates an exothermic chemical reaction that agitates & excites the molecules in an object. This agitated motion of these molecules creates heat. The more they move around the more heat they give off. This heat is transferred through the air and can be felt by us through radiation.
Do aur do paanch kyun nahin? – This is defined by the numeric system – sum of two even numbers is an even number. Now, don’t ask 6 kyon nahin !
Ped ho gaye kam kyon? – Afforestation – trees meet many human needs – paper, rubber, furniture, transport. Also leading to global warming – Al Gore’s fav subject.
Teen hai ye mausam kyon? – Rotation around the suns orbit creates varying intensity from the Sun leading to 3 seasons. In some parts of the country , theres no rain so its more like summer all year round !
Chaand do kyon nahin? – There are two moons ! Earth has two moons; the first one is the one we all know called 'chaand ' the second is 'Cruithne' a 3 mile lump of rock that takes 770 years to cycle its orbit. A collision between our planet and another body created a debris which got caught in our gravity and formed the moon.
Duniya mein hai jung kyon? – This is metaphysical – quite beyond physics. Tribal survival instincts lead to war and will continue to do so. Some parts of the world are still evolving – defining new reasons for fights and redrawing boundaries.
Behta laal rang kyon? – Corollary to the above. Jung leads to laal rang. Purely physical.
Sarhadein hai kyon har kahin? – Purpose keeps vitality, differences create eliminiation of options and Darvinian theory leads to survival of the fittest.
Behti kyon hai har nadee? – All matter flows from high to low till even – rivers originate from the high mountains and hills and flow into oceans
Hoti kya hai roshni? – Millions of tones of Hydrogen is converted into helium every minute in the Sun creating immense heat & light. In the night, the Reflected light from moon gives the ‘roshini’
Dost kyon hai rooth te? – Transactional Analysis in play here. The three stages of Parent – Adult – Child create many permutations of behaviour, one of them is an emotional blackmail. In negotiations when you don’t want to argue logically, you assume a child state and ‘rootho’ , creating a temporary artificial advantage.
Taare kyon hai toot te? –Keep in mind that shooting stars really aren't stars at all. They are debris from space buring up entering earths atmosphere
Badalon mein bijli hai kyon ? During a storm, a build up of electrons in the upper layers of the clouds causes Lightening. These electrons are attracted towards the positive potential of the earth, but air’s stiff resistance doesn’t allow the electricity to pass through easily. When a huge potential has been accumulated, the electricity forces its way through the air molecules. This causes a lot of friction and hence releases a tremendous amount of heat energy causing thunder. Lightning usually strikes the highest point and the most positively charged area. This is becuz lightning looks for the easiest way out of air.
Sanaata sunaee nahin deta – newtons first law- matter remains in motion till external force acts. Sound is created by movement of air molecules. If molecules are static, so sound is ultrasonic and one can’t hear it.
Aur hawaein dikhayee nahin deteen – air made up of various transparent - gases Nitrogen, Oxygen, Argon, Carbon Dioxide, Neon, Helium, Methane, Krypton, Hydrogen and Xenon
