Dhvni tarangon ka paraavartan (reflection of sound)

Prakash ki bharti dhvni ki ek madhyam se chalkar dusre madhyam ke prusth se takrane per pahle madhyam mein Laut aati hai Dhoni ka diwaron se takrakar wapas lautana hi dhone ka paraavartan kahlata hai Jaise kuen dhaatu ki Chadar aadhe se donon tarange paraavartit Ho jaati hai Dhoni ke paraavartan ke liye chikni tatha chamkili satta ki avashyakta nahin Hoti hai|

Dhoni ka paraavartan sikhane AVN kathor prastuton se adhik tatha AVN naram prusthon se kam hota hai isliye Dhoni ka paraavartan diwaron pahadon tatha Prithvi tal sabhi se ho jata hai|

Dhoni paraavartan ke Anya udaharan hamare Dainik jivan mein milta hai yadi ham kisi kuen mein jakar bolate Hain to humne apni awaaz ko aise aate hue sunai deti hai college mein bajate hue loudspeaker ki Dhoni Mul strot ke atirikt kisi sthan se bhi aati Hui pratit hoti hai|
