Two point A and B are situated at the same distance from the phase difference between the light waves passing throught A and B will be

Two points A and B are situated at the same distance from a source of light, but in opposite direction from it. The phase difference between the light waves passing through A and B will be :

An isotropic point source 'S' of sound emits constant power. Two points A and B are situated at distance x and 2x from S. the difference between the loudness of points A and B is about (log 2=0.3)
