Laplas ka Sanshodhan - Tarang Gati ki visheshtaye

Laplas ka Sanshodhan

Newton ke lagbhag 100 varsho baad sann 1816 mei laplas ne newton ki turti ka thhek pata lagakar uske sutre mei santoshprad sanshodhan kiya laplas ne bataya ki newton ka yah vichar ki jab kisi gass  mei dhavani tarangy chalti hai toh gass ka taap sthior rehta hai sahi nahi hai vastva meri jab gasiye madhyam mei dyhavani tarangy chalti hai toh madhyam ke kisi bindu par sampidan tatha virlan ki dasahye ekantra kram se utpann hoti hai sampidan ke samaye utpann hui ushma madhyam se bahar nahi ja sakti hai ttaha virolan ke samaye lop hui ushma bahar se andar nahi aa pati hai iske atirikt ushma ka yah aadan pradan isliye bhi nahi ho pata hai kyoki gase ushma ki kuchalak hoti hai in karno se madhyam ke kisi bindu ka taap sampidan ke samaye badh jata hai tatha virlan ke samaye ghatt jata hai arthatb dhavani tarangy tarango ke chlane par gasiye madhyam mei tap parivartan hote hai yah maan prayog dwara prapt maan ke barabar hai atah lalpas ka sanshodhan thek hai.

Uprokt varnan se yah sopasth hai ki dhavani ki chal vibhinn madhyamo mei bhinn bhinn hoti hai dhavani ki chaal gaso mei sabse adhik kam dravo mei usse adhik tatha thoso mei sabse adhik hoti hai yadi rel ki patri par ek vyakti hathode se chot kare tatha kuch duri par dura vyakti sune toh usey thode samaye ke antar se do dhavanioya sunayi deti hai pheli dhavani patri mei ko hokar pahuchti hai tatah duri vastu vayu mei hokar yadi dusra vyakti apna kaan patri se laga le toh pehle pahuchne wali dhavani tevr lagti hai parantu bad mei pahuchne wali wse hibrehti hai isse yah spasth ho jata hai ki pehle pahuchne wali dyhavani veh hai jo patri mei ko hokar jati hai.

Tarang gati kisi bhotik madhyam mei utpann ek vikshobh hai jo apna swaroop badle bina madhyam mei ek nishchit chaal se aagey badhta hai.

Tarang Gati ki visheshtaye

Tarang gati ki nimn visheshtaye hoti hai-

Yantrik tarango ke sanchran ke liye ek aese pardarthik madhyam ka hona aavshyak hai jise pratyasthta tatha jadatv ke gunn ho.

Tarang gati mei madhyam ke knn ek sthan seb dusre sthan par nahi chla ejate ye kevel apni aoni madhye sthityo kwe pariteh kamp;an karte hai tatha vikshobh ke sath aagey nahi badhte.

Kampan karne wale kano ke vibhinn sthityo mei veg bhinn bhinn hote hai parantu vikshobh ka veg niyat rehta hai jo kevel madhyam ki prakarti par nirbhar karta hai.

Madhyam ke kampan karne wale kramagat kano ke kampan ki kala satat roop se badalti jati hai iska karan yah hai ki madhyam mei utpann vikshobh ke nikattam kan sabse pehel kampan karna prarambh karta hai use apna kann jadatv ke karan kuch der baad kampan prarambh karta hai tatha isey prakar aagey ke kann kampman hote jate hai atah kampan ki kala ek kan se dusre kann par satat roop se badalti jati hai.

Tarang gati mei yadhyapi madhyam ke kann apna sthan nahi chodte hai parantu urja madhyam ek bhag se dusre bhag ki or sanchrit hoti hai.

Kisi madhyam mei do athwa adhik tarangy ek dusre ko prabhavit kiye bina sath sath chal sakti hai.

Do vibhinn madhyamo ke prathakkari tal par aane wali tarangy aanshik parvartit tatha aanshik aparivartit hoti hai.

Anuprasth tarango mei dhurvan hota hai.

Samtal pragami tarang

Yadi ham kisi samang madhyam mei lagatar tarangy utpann karte rahe toh madhyqam ke kann lagatar kampan karte rehte hai is awstha mei madhyam mei utpann hue vikshobh ko samtal pragami tarang kaha jata hai tatah yah alag alag hota hai.
