The sudden increase inpressure and temperature from lightning produces rapidexpansion of the air surrounding and within a bolt of lightning. Inturn, this expansion of air creates a sonic shock wave, similar to asonic boom, which produces the sound of thunder The cause ofthunder has been the subject of centuries of speculation andscientific inquiry. The first recorded theory is attributed to theGreek philosopher Aristotle in the third century BC, and an earlyspeculation was that it was caused by the collision of clouds.Subsequently, numerous other theories were proposed. By themid-19th century, the accepted theory was that lightningproduced a vacuum. In the 20th century a consensus evolved thatthunder must begin with a shock wave in the air due to the suddenthermal expansion of the plasma in the lightning channel.5 VISION ow visionias at facebookhttp://twitter.com/#!/visionias

But when the sun islow in the sky we can see far off objects near the horizon that weknow are big and we imagine that the sun is even bigger.Theapparent change in size is an optical illusion.Option-2( Colour of the sun at dawn) is an optical illusion.Light is made up of lots of colors. And out of all those colors, red isthe one that travels the farthest.That means is that red is the lastcolor seen, when the sun sets. When the sun is setting, all of thosecolors are slower-moving, and it is no longer bright outside,because the colors are all moving at a separate pace. The othercolors start disappearing, and red (being the fastest), is what is lastseen.Option-3( Moon being visible at dawn) is NOT an optical illusion.The moon is visible somewhere in the sky at dawn during theentire half of the cycle of phases from Full Moon to just beforeNew Moon.It is not an optical illusion.Option-4( Twinkle of stars in the sky) is an optical illusion.Stars continuously emit light. These light travels through variouslayers of earth atmosphere before they reach our eyes. Nowrefractive index decreases as we move from down throughatmosphere. So light keeps on getting bent towards normal ateach point of incidence. Practically there are infinite points ofincidence as refractive index keeps changing as we move down.This happens in accordance and finally light reaches our eye. So wesee the star at B but actual position of star is at A. Furtheratmospheric conditions keeps on changing. Hence light fluxreaching our eyes keeps varying and so star appears bright atsome time and it appears fade at other. So starts apparentlytwinkles but practically they don't.Option-5( Polestar being visible in the sky) is NOT an opticalillusion.The sky appears to rotate around points called the celestial poles(one north pole and one south pole). These points represent thedirections where the Earth's rotation axis points.Thus, for a fixedobserver on Earth, a celestial pole would always be in the sameNCERT Class X: Science chapter10Science andTechnology39CCMFA9 VISION ow visionias at facebookhttp://twitter.com/#!/visionias

direction (due north or due south, depending where we are), andits altitude over the horizon would be equal to our latitude.Polarisis not exactly at the celestial pole; it is less than one degree from it(so that it is hard to tell the difference without measuring) makingit a good indicator for the pole -- that is why it is called the PoleStar.40414243Rainbow is produced when sunlight falls ondrops of rain.

Viruses are transmitted from oneorganism to another by biological vectorsonlyNCERT Class X: Science Page 194Science andTechnologyDMFEMOption:-1Each individual droplet of water acts as a tiny prism that bothdisperses the light and reflects it back to our eye.Option:-2Since water is more dense than air, light is refracted as it entersthe drop.Option:-3Some of the light will reflect off the back of the drop if the angle islarger than the critical angle (48 for water).RRNewly transplanted trees or shrubs experience some degree oftransplant shock. This is simply the plant reacting to having beenmoved. It is generally caused by damage to the roots of the plantduring the transplant. While the thickest roots are nearest to theroot ball, the most important roots, those that actually "do thework", are located the farthest away from the plant. These tinyroots are covered by even tinier hairs which absorb most of thewater that is eventually carried to the top-growth of the plant.During a transplant, these fine roots are usually destroyed eitherby being cut to keep the root ball size down, by drying out (someaccounts say it only takes 3-4 minutes of exposure to air for theseto die), or simply by being jarred and jostled around in the move.As a result of the loss of these feeder roots, the plant is not able todraw the amount of moisture it requires to thrive and grow. Theresulting imbalance between the moisture demands of the topgrowth and the reduced ability of the roots to meet thosedemands manifests as transplant shock.EMa and d statement does not say anything about the country X, onlythe general world economy.
