Radio Waves Information In Urdu Radio Waves Details In Hindi

Radio Waves Wavelength Frequency And Energy


Radio Waves electromagnetic spectrum kay part ko banati hain. Ye waves wavelengths ke faraq ke sath energy ke packets hote hain aur visible light waves, X-rays ya gamma rays se milti julti hoti hain. Aik radio wave dusre electromagnetic waves ki tarah ocean surface wave ya phir dusri kisam ke wave ki tarah hoti hai. Radio waves ki dono iqsam hill yani pahar aur valley shape ki tarah hoti hai aur ye bar bar apne aap ko doharati hain. Aik wavelength ko uske samne wali wavelength ke top se le kar uske apas ke fasly k mutabiq measure kiya jata hai.
Visible light ki wavelength bohat zyada choti hoti hai ye 1 micrometer se le kar insan k 1 baal ki motai se bhi choti hoti hai. Radio waves ki wavelength Centimeters se le kar meters tak ho sakti hai. Iski radio frequency bhi hoti hai. Sab se choti radio waves ko microwaves kaha jata hai. Shortwaves bilkul choti nahin hoti. Medium or long waves bhi hoti hain.


Antennas ko Radio waves send aur receive karne ke liye design kiya jata hai radio waves istemal hone wali wavelength ke size se milti julti hain. Bohat saray radio antennas jis tarah cars mein antennas lage hote hain unhen lamba banaya jata hai kyon ki wo FM Radio ke signals receive karte hain jo ke kuch meters aur kuch feet tak hote hain aur AM Radio jo ke hundreds of meter ya phir thousand of feet tak ho sakte hain.
Manmade radio waves ko 19th century se communication ke liye istemal ho rahi hain. Radar ko 20th century mein develop kiya gaya jo radio waves ko istemal karta hai aur door ke objects ko dekhta hai. Radios bhi information ko send aur receive karne ke liye waves ko istemal karte hain.

Who Discovered Radio Waves And When


Natural radio waves ko pehli bar 1930s mein Karl Guthe Jansky ne Bell Laboratories mein kaam karte hue discover kiya tha. Iski discovery se pehle har koi sochta tha kay sirf log radio waves ko generate kar sakte hain. Aaj kal radio waves ko bohat sari cheezon ke istemal kiya jata hai. Broadcasting aur communications Satellites aur Mobile Phones iske ilawa bohat saray Computers aisay hain jo radio waves ke zariye communicate karte hain.
