    Questions 2. [1] Wavefronts represent all points of the wave cycle. This statement is: correct, incorrect. [2] Wavefronts are: the forward sides of a wave, the backward sides of a wave, wavelengths, geometric shapes, points of both maximum and minimum values. [3] Sound propagates through the air. Wavefronts are drawn to show where the air undergoes a maximum compression. Halfway between two successive wavefronts, the air: undergoes a maximum compression returns to normal, undergoes a maximum expansion, somewhere between a...

    In the figure, a sound of wavelength 0.700 m is emitted isotropically by point source S. Sound ray 1 extends directly to detector D, at distance L = 11.9 m. Sound ray 2 extends to D via a reflection (effectively a "bouncing") of the sound at a flat surface. The reflection occurs on a perpendicular bisector to the SD line, at distance d from the line. Assume that the reflection shifts the sound wave by 0.500λ. For what least value...
