Laser Microphone

[Carl Fredrik Ahl]

Hi,

I wonder how the laser coming out from a laser microphone gets affected by sound waves. 

[Sensei]

Sound wave after reaching window in the room is causing shaking of the glass accordingly to power and frequency of the sound. Laser pointed at window from outside is disturbed accordingly by movement of the glass.
