Light passes through a pair of very thin parallel slits. the resulting interference pattern is viewed far from the slits at various angles theta relative to the centerline coming outward from the midpoint between the slits. the central bright fringe is at theta = 0 degree. if the central bright fringe has intensity i0, what is the intensity of the next bright fringe on either side of it

Sounds propagates through some kind of medium. usually it's air, but it goes just as well through solid objects like walls, windows etc. a soundwave will compress the (air)molecules in front of it, and if this increased density wave hits your ears, you register it as sound. solid objects like walls are a lot denser than air, this means that they will damp a wave, but also carry it easier.
