."Radio waves" transmit music, conversations, pictures and data invisibly through the air, often over millions of miles -- it happens every day in thousands of different ways! Even though radio waves are invisible and completely undetectable to humans, they have totally changed society. Whether we are talking about a cell phone, a baby monitor, a cordless phone or any one of the thousands of other wireless technologies, all of them use radio waves to communicate.
in tamil.
the first radio is invented by the markoni.
Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width.[n 1] When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.
Radio systems need a transmitter to modulate (change) some property of the energy produced to impress a signal on it, for example using amplitude modulation or angle modulation (which can be frequency modulation or phase modulation). Radio systems also need an antenna to convert electric currents into radio waves, and radio waves into an electric current. An antenna can be used for both transmitting and receiving. The electrical resonance of tuned circuits in radios allow individual stations to be selected. The electromagnetic wave is intercepted by a tuned receiving antenna. A radio receiver receives its input from an antenna and converts it into a form that is usable for the consumer, such as sound, pictures, digital data, measurement values, navigational positions, etc.Radio frequencies occupy the range from a 3 kHz to 300 GHz, although commercially important uses of radio use only a small part of this spectrum.

Background music volume சற்று குறைவாக இருந்தால் இன்னும் சிறப்பாக இருந்திருக்கும்

[@Akash-vx4ly]

Bro video ok but background sound athigama iruku

[@ChandraKumar-gm6ml]

Music மட்டும் தான் இந்த பேச்சில் அதிகமாக இருக்கிறது

[@Aswinth9952]

I need more videos.. Communication related topics

[@manoharanmano9103]

Neenga enna patichinga

[@akshathnasir1632]

Plz avoid tha background bgm

[@elayaraja2176]

Bro don't need background music...

[@mallihaSaha]

Modulate the Demodulate Various signal using AM/FM Tratner kit 😊 EM Anna

[@poongodivelu8505]

Background music volume korachi vainga voice kekave la sariya

[@freefiremk3192]

Class super but background music cut panuga semma clear

[@naveenk7570]

explanation is not enough..

[@aswinharsha5854]

Pls explain amplitude modulation , frequency modulation, phase modulation

[@bhuvakarthik2984]

nice and useful video

[@mallikrish1719]

Bro avoid backround sound

[@nallasivamc8388]

amplitude modulation na enna nnu simple la oru video poodugga bro

[@herosoundsystem3652]

Bro I want transistor configurations .cb.CE.cc explain in theory

[@androidkumar992]

U pl go n study basic...

[@androidkumar992]

Yes..innum konjam technical information venum...n bare a sollathinga..neria examples sollanum dear.. okay? Am also an engineer..👍

[@AshokKumar-od8tt]

Bro transduser poduga

[@PRAVEENKUMAR-ju8oj]

Background sounds erukuradhunala nega peasuradhu keakala bro

[@vasanth.r322]

please explain for pulse typs and explain types detailed with drawings in Tamil explaing

[@imthiyasm1159]

nice bro.Daily video podunga bro

[@sasikumarstephenp8208]

Please give thyrister related video

[@sasikumarstephenp8208]

U r awesome bro. I like ur all videos

[@parantastys4457]

Bro different between tone squelch and carriere squelch from wireless radio comn pl ans

[@AshokKumar-od8tt]

Transducer bro

[@hemachandrika1044]

plz cut the background sound 😐😐

[@gunabsc6386]

Eppadi bro fm chennal seiyarathu

[@JV_DECORATIONS_THANJAVUR]

Bro oru what'sapp group open pannunga. Invite link ah description la kudunga

[@suncontrols1884]

Ji max3430 ic details sollung please

[@svector6667]

konjam slow aah sollunga bro...but nice video

[@RajeshSriMuthu]

so useful bro, how electromagnetic wave (ex. radio wave) is produced, explain in simple circuit

[@abinashram680]

hi bro....this video explaination is gud....i have a doubt that how the carrier signal carry the message signal ?

[@indhumthilakshmi9018]

Frequency spectrum of am wave solluga

[@hariiharannn6489]

Ulti ya yoww

[@lokeshmohan210]

Bro post video about satellite communication

[@kashinikuttyinarataigal6019]

Hartley oscillator video iruka

[@kathiresanhaipriyankailove4346]

hai na very useful anna itha tamil la translated panni sonna easiya irukum i love physics.

[@tricksandtips001]

super bro

[@sathyakumaravel995]

i want more informayion in digital modulation

[@manimaranb8621]

I want more information

[@sivam02]

all the best

[@bharathi.k4449]

Bro konjam VSB explain pannuga

[@sanjeeviraja6624]

Music low pannunga

[@mallihaSaha]

w

[@AshokKumar-od8tt]

Control system

[@naveenalaila1852]

More speed Konjam slow Cheidal super very good thanks

[@vetrivel9995]

Modbus and profibus communication working sollunga

[@sundarmoorthy4742]

Modulating signalin amplitude ku yetrar pola carrier signalin frequency, amplitude, phase matram yerpadum, so modulating signal constant

[@sundarmoorthy4742]

Please check your explanation in amplitude, frequency, phase modulation

[@krishk4870]

Bro thayavusenju intha bgm ah cut pannunga ila unga voice mic ah sari pannunga irritating bro antha bgm pls take it as a feedback..

[@senthilvel51]

hi bro ...na networking line ..so ungalala ennota job Ku konjam tips kutukka mutiuma ...tech line la

[@senthilvel51]

STUDENTS CORNER its ok bro ... thanks for the response ...well done.

[@mallihaSaha]

Best
