419. How do we judge the direction of a sound?

We can get the direction of sound only because we have two ears. The sound waves reach the right and left ear with a small time difference because the ears are at slightly different distances from the source of sound. The ear drums vibrate and the ear ossicle transmits the impulse to the inner ear. The inner ear sends it for the to the brain where the signals from both ears reach at marginally different times. The brain calculate the direction of the sound from the tiny difference in these times.
 
418. How does a motion detector light work?

Motion detectors are small electronic eyes that detect infrared waves—heat waves that radiate from moving objects. When the detector senses an object moving across its field of view, especially warmer objects such as people, animals and cars, it electronically turns on the lights. This technology is also used in Motion Sensor Cameras for security purposes.
