light travels faster than sound then why do we hear sound
first and not video in telivision?
Answer Posted / monk
the video signal donot move with the speed of light but
with the speed of the carrier wave.
the video is amplitude modulated and audio is frequency
modulated signal and AM takes more time for transmission
than Fm signals.
hence we hear sound first and not the video in the Tv
