Q- In a location where the speed of sound is 354 m/s, a 2000 Hz sound wave impinges on two slits 30.0 cm apart.
(a) At what angle with the perpendicular bisector of the slits is the first maximum located?
(b) If the sound wave is replaced by a 3.00 cm microwave, what slit separation gives the same angle for the first maximum?
(c) If the slit separation is 1.00 micro-meter, what frequency of light gives the same angle for first maximum?
