The spot that draws the picture on the TV screen sweeps across the screen 15,750 times every second.
At the same time, it's sweeping from top to bottom of the screen 60 times every second. In that way,
it draws the picture as a stack of horizontal lines on the screen.
The spot is the front end of a beam of electrons that shoot at the screen from the rear of the
picture tube. It gets steered around by electromagnetic coils around the neck of the picture tube.
The coils are driven by voltages produced in the electronics of the TV set.
The high-pitched sound you hear is the 15.75 KHz alternating voltage that sweeps the beam
side to side across the screen.

Why does hydrogen explode with a squeaky pop if you put a lighted splint into it?
When a lighted splint is introduced to hydrogen gas, it ignites due to the gas's flammability, resulting in a small explosion characterized by a squeaky pop sound. This occurs because hydrogen reacts rapidly with oxygen in the air to form water vapor, releasing energy in the form of heat and sound. The "pop" is a result of the rapid expansion of gases and the shockwave produced by the combustion reaction. The sound is high-pitched because of the low mass of the hydrogen molecules involved.
What gas goes pop?
