I'll try my best to give all possible Physics Questions.
I gave this name to blog "All Interview Physics" only because here are questions about physics
we can hear our friend around corner but can't see him, it is due to phenomena of diffraction. sound wave has large wavelength, which is comparable to size of corner , so it can diffract and after diffraction of sound wave we can hear our friend. while wave length of light is much smaller then the size of corner, so it can diffract through corner and that's why we can't see our friend

The thing is that light has very small wavelenght compared to sound so it diffracts round the corner as sound is 3Dimentional
