Question

Explain in brief the working of a television.

Answer 1

A television basically consists of three parts: the TV camera that turns a picture and sound into a signal; the TV transmitter that sends the signal through the air; and the TV receiver (the TV set in the home) that captures the signal and turns it back into picture and sound. TV creates moving pictures by repeatedly capturing still pictures and presenting these frames to your eyes quickly that they seem to be moving. The images are flickering on the screen so fast that they fuse together in your brain to make a moving picture.
