In a location where the speed of sound is 332 m/s, a 2,000 Hz
sound wave impinges on two slits 30 cm apart.
(a) At what angle is the first-order maximum located?
°
(b) If the sound wave is replaced by 4.60 cm microwaves, what slit
separation gives the same angle for the first-order maximum?
cm
(c) If the slit separation is 1.00 μm, what frequency of
light gives the same first-order maximum angle?
Hz
