An aircraft maintenance technician walks past a tall hangardoor that acts like a single slit for sound entering the hangar.Outside the door, on a line perpendicular to the opening in thedoor, a jet engine makes a 600-Hz sound. At what angle withthe door will the technician observe the first minimum insound intensity if the vertical opening is 0.800 m wide and thespeed of sound is 340 m/s?

Two small slits are in a thick wall, 27.5 cm apart. A sound source from the behind the wall emits a sound wave toward the wall at a frequency of 2,000 Hz. Assume the speed of sound is 342 m/s. (a) Find the (positive) angle (in degrees) between the central maximum and next maximum of sound intensity. Measure the angle from the perpendicular bisector of the line between the slits.  ° (b) The sound source is now replaced by a microwave antenna, emitting microwaves with a wavelength of 2.75 cm. What would the slit separation (in cm) have to be in order to give the same angle between central and next maximum of intensity as found in part (a)?  cm (c) The microwave antenna is now replaced by a monochromatic light source. If the slit separation were 1.00 µm, what frequency (in THz) of light would give the same angle between the central and next maximum of light intensity?  THz

Microwave ovens typically cook food using microwaves with frequency 2.45 GHz. What is the corresponding wavelengh of these microwaves in cm?(ans: 12.2cm)   An oceanic depth-sounding vessel surveys the ocean bottom with ultrasonic waves that travel 1530 m/s in seawater. If the time delay of the echo is 6 seconds, what is the depth of the water? (ans: 4590 m) Show work

Two identical speakers are initially equal distancesfrom a listener . Thelistener hears a sound maximum (constructiveinterference). When the upper speaker is moved backby a distance d = 2 m, the listener hears a soundminimum (destructive interference). What is thelongest wavelength the soundwaves could have?
