* Detecting insects by diffraction of sound A biologist builds a device to detect and measure the size of insects. The device emits sound waves. If an insect passes through the beam of sound waves, it produces a diffraction pattern on an array of sound detectors behind the insect. What is the lowest-frequency sound that can be used to detect a fly that is about 3 mm in diameter? The speed of sound is 340 m/s.

- Sound with a frequency 650 Hz from a distant source passes through a doorway 1.10 m wide in a sound-absorbing wall. Find (a) the number and (b) the angular directions of the diffraction minima at listening positions along a line parallel to the wall.arrow_forwardFigure P36.35 shows a radio-wave transmitter and a receiver separated by a distance d = 50.0 m and both a distance h = 35.0 m above the ground. The receiver can receive signals both directly from the transmitter and indirectly from signals that reflect from the ground. Assume the ground is level between the transmitter and receiver and a 180 phase shift occurs upon reflection. Determine the longest wavelengths that interfere (a) constructively and (b) destructively. Figure P36.35 Problems 35 and 36.arrow_forwardA student holds a laser that emits light of wavelength . The laser beam passes through a pair of slits separated by a distance d, in a glass plate attached to the front of the laser. The beam then falls perpendicularly on a screen, creating an interference pattern on it. The student begins to walk directly toward the screen at speed v. The central maximum on the screen is stationary. Find the speed of the mth-order maxima on the screen, where m can be very large.arrow_forward

- Which of following statement regarding holography is incorrect? A. Unlike a photography, the holography records both amplitude and phase information of the imaged objects. B. An optical hologram is produced through two beam interference, while image is reconstructed through light diffraction. C. Since several types of holograms can be reconstructed using regular white light, these holograms can produce and show true color images. D. When reconstruction beam only illuminates a small section of a hologram, one can still see whole image of the recorded object with lower resolution.arrow_forwardPlease help me with these questions An antenna broadcasts 600 MHz waves. a.
