Why do we hear an annoying loud sound when a switched on speaker and mic is brought together/ brought nearer? ( This happens now and then during some functions,.)
And my other question is Why do we see propogating lines when a Televison screen is captured in an Handycam? (A wave like things, that distorts the video quality)
