Q2 By this question and answer, having searched to defend Mr Narayanasamy) Mr Gopalakrishnan answered all the doubts raised by Mr Narayanasamy, which lab? Rajaram lab; and all other flow of words; energy top middle end etc etc. Thank you . So Solar molecules, atoms, Photons etc are taught to Narayanasamy by his disciple Mr Gopalkrishnan.
The error of the question is simple in this Q & A. Light energy does not take 20000 years; as a matter of fact the origin of light (NOT THE LIGHT) [THE SOURCE OF LIGHT WHICH IS YET TO BECOME THE LIGHT] (TO BE PRECISE, SUGAR CANE IS IN THE GODOWN WHICH IS NOT SUGAR FOR SOME DAYS; ONEDAY SOME SUGAR CANE IS TAKEN OUT TO THE MACHINE AND THAT PROCESS TURNS THAT CANE, LATER AS SUGAR. So why so many days for sugar cane to machine but sugar immediately -is not a relevant question. Atoms have many names, and one is photon. Photon nature emanated from its source. AND THAT MAY HAPPEN FROM 100 YEARS TO 170000 YEARS (NOT 20000 ONLY) ; THAT MEANS FROM THE CENTER OF THE sun, Hydrogen helium etc reacts in high heat spinning around and that action might take so many years as calculated below by calculus work out, which is not photon or light. I can explain the atomic bomb, stay in store , in flight only as a bomb. When it explodes only SO MUCH OF LIGHT PHOTON IS CREATED. So keeping a bomb under the process alone might take so many years. THAT EXPLOSION IS CALLED “FUSION”. ONLY WHEN FUSION OCCURS PHOTON IS GENERATED; AND THAT IS GENERATED WHEN IT REACHES THE SURFACE. TILL THEN IT IS ONLY AN ATOM BOMB. ON SURFACE ALSO THAT FUSION MUST OCCUR. ONCE DONE, PHOTON TAKES THAT TIME TO REACH THE EARTH. The calculation those who knew may: Researchers can measure the intensity of sunlight using a sunshine recorder, pyranometer, or pyrheliometer. To calculate the amount of sunlight reaching the ground, both the eccentricity of Earth's elliptic orbit and the attenuation by Earth's atmosphere have to be taken into account. The extraterrestrial solar illuminance (Eext), corrected for the elliptic orbit by using the day number of the year (dn), is given to a good approximation by [image: image.png] where dn=1 on January 1; dn=32 on February 1; dn=59 on March 1 (except on leap years, where dn=60), etc. In this formula dn–3 is used, because in modern times Earth's perihelion, the closest approach to the Sun and, therefore, the maximum Eext occurs around January 3 each year. The value of 0.033412 is determined knowing that the ratio between the perihelion (0.98328989 AU) squared and the aphelion (1.01671033 AU) squared should be approximately 0.935338. The solar illuminance constant (Esc), is equal to 128×103 lux. The direct normal illuminance (Edn), corrected for the attenuating effects of the atmosphere is given by: [image: image.png] where c is the atmospheric extinction and m is the relative optical airmass. The atmospheric extinction brings the number of lux down to around 100,000 lux. The total amount of energy received at ground level from the Sun at the zenith depends on the distance to the Sun and thus on the time of year. It is about 3.3% higher than average in January and 3.3% lower in July (see below). If the extraterrestrial solar radiation is 1,367 watts per square meter (the value when the Earth–Sun distance is 1 astronomical unit), then the direct sunlight at Earth's surface when the Sun is at the zenith is about 1,050 W/m2, but the total amount (direct and indirect from the atmosphere) hitting the ground is around 1,120 W/m2. In terms of energy, sunlight at Earth's surface is around 52 to 55 percent infrared (above 700 nm), 42 to 43 percent visible (400 to 700 nm), and 3 to 5 percent ultraviolet (below 400 nm) At the top of the atmosphere, sunlight is about 30% more intense, having about 8% ultraviolet (UV),[8] with most of the extra UV consisting of biologically damaging short-wave ultraviolet. Direct sunlight has a luminous efficacy of about 93 lumens per watt of radiant flux. This is higher than the efficacy (of source) of artificial lighting other than LEDs, which means using sunlight for illumination heats up a room less than fluorescent or incandescent lighting. Multiplying the figure of 1,050 watts per square meter by 93 lumens per watt indicates that bright sunlight provides an illuminance of approximately 98,000 lux (lumens per square meter) on a perpendicular surface at sea level. The illumination of a horizontal surface will be considerably less than this if the Sun is not very high in the sky. Averaged over a day, the highest amount of sunlight on a horizontal surface occurs in January at the South Pole (see insolation). K RAJARAM IRS 27 923 Q3 If you drive in India you won't be able to drive in the UK, USA, AUSTRALIA as stated. That is a bad remark. It is tough to drive in those places as so many rules may have to be observed as well as high speed control and side driving habits must be cultivated. Without a map one cannot drive there. Here you can park and ask for places; there you cannot park as you like and if you miss the turn must do so many gimmicks to come back to take the turn.
