Why does the flash on a digital camera emit a sound when it goes off?
Answers:
There are 2-3 different sounds happening when the flash goes off:
* One is the shutter opening/closing
* An artificial sound generated through the camera's speakers to tell the user that the shot has been taken (coz unlike as in the case of a film camera, u cant really feel when the snap has been taken)
* The sound of discharging of the capacitor used to store the charge to provide for the high illuminating flashbulb. The source of this sound is the same as that during thunder.
Other answers:
because of the light and your eyes are part of you ears to so if your camra does that thats just the soulnd of the high powered light Because the capacitor has stored very high voltage (it could shock the pee out of you) and when the flash is discharged it flashes the flash tube creating a lot of heat. It lasts only a few thousands of a second but that discharge causes a pop sound.
