In a double-slit experiment, if the slit separation is increased by a factor of two, what happens to the interference pattern shown on the screen? What happens if the wavelength is halved? What happens if the distance to the screen is double?
Two small forward-facing speakers are 2.50 m apart. They are both emitting, in phase with each other, a sound of frequency 1100 Hz in a room where the speed of sound is 344 m/s. A woman is standing opposite the midpoint between the speakers and is initially 35.0 m from the midpoint. As she slowly walks parallel to the line connecting the speakers, at what angle ? (relative to the centerline coming outward from the midpoint between the speakers) will she first hear no sound?
