An a location where the speed of sound is 344 m/s, a 2000 Hz sound wave impinges on two slits 30 cm apart.
a) At what angle is the first maximum located?
b) If the sound wave is replaced by 3.00 cm microwaves, what slit separation gives the similar angle for the first maximum?
c) If the slit separation is 1.00 µm, what frequency light gives the same first maximum angle?
